A geographical guide through UNESCO's extensive list of world heritage sites.

UNESCO's list of world heritage sites is a great

While researching UNESCO's list it appeared that a lot of world heritage sites are related to other geographical features. As an example the "Frontiers of the Roman Empire" was listed as a single coordinate. However it's description is referring to 10 different locations all around Europe. By showing all of these locations a much better impression of the actual scale and size can be given.

After finding a large number of sites that were in need of multiple geographic references this interactive map was born.

Simple algorithm for crowd simulation inspired by praying muslims at the Tahrir Square in Egypt. After seeing these beautiful patterns emerge from thousands of people simultaneously performing a single ritual I was interested in figuring out how these patterns developed.

As seen in the image above the praying people align themselves relative to each other forming wavy rows. These rows diverge and different rows begin to form in between those rows. This algorithm is a study into trying to dissect this behavior into simple rules. Once all rules are defined we can start simulating agents that follow those rules.

Rules derived from the picture above:
  1. Agents can only only be placed relative to another agent (cohesion)
  2. Agents prefer to be placed alongside each other to form rows. Only a small percentage of agents gets placed above or below their spawn point (forming rows)
  3. The orientation of agents is slightly offsetted from their neighbors (wavy rows instead of straight lines)

The video above shows a debug view of the simulation. Red areas around agents mean that there's room for another agent in that direction. This information is used for rule 1 and 2.

Through the simulation of hundreds of extremely simple agents seemingly complex behavior can simulated. As seen from the final result below: agents match the behavior of the people seen in the picture.

For this project commissioned by the GoShort Festival we were asked to create an interactive and intuitive version of the festival programme on a large touchscreen situated at the entry of the festival.

All the shorts are given their own identity by using each frame of the film to create unique slitscans. This method also gives the viewer an impression of the colors and atmosphere of the film.

The programme consists of movies grouped in themed blocks. By layering all the slitscans for every block it’s easy to get an overview of the atmosphere of the complete block without having to leave the main interface layer. If you are interested in a block it’s just a matter of tapping the block and all the movies will pop out.

A concept for a future global energy management scenario where every city generates it's own electricity. If the city has overcapacity it can distribute to the 10 nearest cities to catch spikes. Cities can also request power from neighboring cities if their own demand exceeds their own supply. By linking cities around the globe we end up with a decentralized free-flowing energy distribution system that can absorb outages and other catastrophes.

I developed an application to see the concept in action. The gray band moving from right to left represents the day/night cycle. At daytime a city will consume more power and when night falls the consumption will decrease. You can zoom and pan on the map. Space toggles a world map (internet connection required).

This project aims to explain the inner workings of the BitTorrent protocol. When you create a torrent from files those files get chopped up in to a hundreds of chunks. Those chunks are distributed across all peers that are downloading the same file. Because the torrent's contents are scattered across all downloaders your computer has to request and reassemble all these chunks back into the original files.

With this installation I'm visualizing the whole process behind downloading a torrent. All the peers—people downloading the same torrent— are displayed on a world map. All chunks—a small part of the torrent's contents—are displayed on a big computer screen. Any connection that transmits data between the peer and the computer is represented by a line from the peer's location to the actual chunk that's being downloaded.

The video below is an impression of the installation in action. This work was on display at the ArtEZ 2012 graduation show.

A series of data visualizations for a generative publication that can be published weekly without human intervention: the Wikipedia vandalism report.

Through the Wikipedia API all modifications to all wikipedia articles were stored for automatic processing. An algorithm was created to determine if an edit was malicious or genuine.

Every week the algorithm ran over the data collected in the previous seven days to determine which articles suffered most from online "vandalism". Reflecting world-wide sentiments on subjects like the news and pop culture. Articles on the "Tea Party movement", "Dancing with the stars", "The Notorious B.I.G", "Fred Phelps" and Wikipedia's own "Administrator intervention agains vandalism" were top ranking vandalism targets.

The graph above shows 7 days of heavy modification on the Tea Party movement article. Users are listed on the right, individual edits are represented on the left. The length of each bar represents the total length of the article after the edit has been applied.

Distribution of malicious (red) and regular edits (green) on an article about Ei-ichi Negishi, a Japanese chemist. This graph was generated right after he won the 2010 Nobel Prize in Chemistry. Apparently reason for both positive and negative attention.
Philips approached us (Jonas Groot Kormelink and I) to create a concept for their new wearable body sensor.

We came up with a concept where your house adapts to your current mood and level of exhaustion. The bracelet collects information about your vitals and transmits this data to your connected devices.

For example: your coffee maker will pour you an extra strong coffee based if you're tired. Your TV will start on a channel that matches your level of excitement and the lightning in your house will also match your mood.

Our concept has been presented at the Philips Design HQ in Eindhoven.
