Accenture Digital Hackathon 2016


Last weekend I took part of Accenture’s Digital Hackathon, a global event organised by Accenture (Duh!) in which more than 400 participants from 8 cities around the globe would try to think of and complete a project within 24 hours under the umbrella theme of “Connect. Collaborate. Create”.

It was my first time at a hackathon and although it required a lot of energy and very little sleep, it was lots of fun and quite an experience with very interesting results from all the talented people who participated.

Designing the new prEmo – An empirical research on how to improve the emotion measuring tool

premo2A while back I was working together with Pieter Desmet, an associate professor at the Industrial Design faculty of the TU Delft, in a project aiming to improve prEmo, a tool to measure emotions towards products.

The tool proved to be very effective, but it still had some points to it that could be enhanced, so that’s why we started working on a newer version of it.

For anyone interested in this kind of studies, you can download a copy of the final document that I wrote reporting on the steps that were followed, the methodologies used, and of course the results from our study.

Hema themed Internet Explorer

Hema Internet explorerAs part of a visual design exercise at the TU Delft, we were given the following assignment:

Hema has signed a contract with Microsoft and will be the first to launch its Hema own brand Internet browser onto the market. The browser will be an Hema version of Microsoft Internet Explorer 6. The contract does not allow Hema to make any modifications to the technology used or the functions provided by the browser. By enforcing these restrictions, Microsoft wants to ensure that consumers are aware that they are using a Microsoft product. As Hema does not specialise in software, it has no objections to the restrictions. The company sees no future in software that has been developed by a warehouse. On the other hand, the company has years of experience successfully marketing well-known products under Hema’s own label.

Assignment A: Design the graphical user interface (GUI) for the Hema browser, based on the functions provided by Internet Explorer 6. Do not waste time altering any of these functions!

The Virtual Bathroom – website

While working at 3D capacity, I was given the task to design the website for The Virtual Bathroom (, a new concept for the communication of bathroom installations which makes use of interactive 3D and videos to create an immersive user experience. – Logo and website design for a Colombian button manufacturer

Botoneria - LogoBotoneria Ltda. (formerly known as La Piacentina) is a button manufacturer in Bogota, Colombia.

They asked me to design a new logo for them and to develop a simple website to showcase their work and production possibilities.

The new logo was inspired by the unique mixture of creativity and technical know-how that characterizes them.

Club Alpine Mulhouse – CTC logo

The Mulhouse fraction of the french Club Alpine asked me to design a logo for a new campaign they were implementing called the Cellule Transport en Commun – CTC (Shared Transportion Cell), which encouraged their club members to use shared transportation means to the climbing trips organized by the club.

I made these two proposals. The first one is a playful reference to the word cell in a biological sense, while giving it a transportation connotation by the shape of a bus being recognized within the cell.

The second one was more to the point and was inspired in traffic signs.

Mexico2 – Logo

Mexico 2 was a proposed new business citadel to be constructed in the heart of Mexico which would become a new focus of economic importance for the whole of the Americas.

At 3D capacity, we were approached to work on the visualization of the project and as part of it I designed this logo. It is based on the idea of the new citadel being a focus point of the Americas and as can be seen the X is an abstraction of a map of the entire continent. The number 2 is placed as superscript to show that Mexico 2 is not merely seen as a second version of something but as an exponential enhancement of the current status. The colours used are the national colours of Mexico (namely red, white and green). The X2 can also be used as a separate image that still conveys the proposed message without including the text Mexico on it as can be seen to the left. – Evi Malisianou’s design portfolio

Evi Malisianou is a very talented greek interaction designer and together with her we designed and set up her online portfolio at
The website’s design is quite simple and clean, giving a nice and playful overview of the projects she has worked on. It is made entirely in flash but easy to update by editing a simple text file to add new projects.

3D capacity – Flash based project management system

This is a project management system that I put in place for 3D capacity‘s website. It is made in flash supported by xml files containing the project data. With it, it was possible to keep all the relevant information (delivery dates, contacts, file folders and communication) in a single place for both 3D capacity staff, as well as for the clients.

By clicking on the screen-shots below you can see a demo of how it works (except for the possibility to save data which is not supported).

Club Alpine Mulhouse – T-shirts

The Club Alpine Mulhouse asked me to design a T-shirt for the club which can be used by club members during the different outdoor activities that are regularly organized.

I designed this T-shirt which can be made in two different colours:

Icons for various applications

Over the years, I’ve designed a series of icons for different applications, such as being used within websites or graphical user interfaces. This is a collection of some of them.

3D capacity’s website

3D capacity is a company specialized in the field of 3D visualizations. I was given the task of developing their website, which should include a log-in system and a project management system.

Imagine – an exercise on visual corporate identity

Imagine - 01During a course at the TU Delft as part of my Industrial Design Engineering BSc., we were asked to work in a design assignment in a group as if we were an actual design studio working for a given client.

As part of the exercise, we had to develop a corporate identity for our studio and use it at all times during the course’s process.

I designed a logo, website, powerpoint starting screen, business cards and even a promotional gift (a mug). – Logo and website

The Virtual Maquette (virtuele maquette in Dutch) is 3D capacity‘s main product, and they wanted to make a simple separate website with a logo of it’s own, in which they could show the benefits of the virtual models through a presentation video.

Colombiactiva logo

Colombiactiva Logo - horizontalThe Colombiactiva Foundation is a non-profit organization, established in March 2007 in Delft, The Netherlands. The Foundation was established by a group of young professionals that work as volunteers, and are aware of the social realities of Colombia. The group feels the responsibility and the compromise to take action to reduce poverty, lack of opportunities and the indifference of people towards these problems.

EVOlving: A concept design for Evi Malisianou’s portfolio website

This was a very graphical proposed design for Evi Malisianou’s Interaction Design online portfolio ( It was meant as an experimentation with an unusual graphical layout and with playful yet simple interactive tricks, such as the faces following the mouse cursor with their eyes.
