Elovalo Effect Challenge

September 05, 2012

Elovalo Effect Challenge

The purpose of Elovalo project (elovalo.org) is to produce three pedestals with a led cube (512 leds) on top of them for Jyväskylä's City of Light event. The pedestals will be visible at a local park.

This challenge is meant to encourage programmers to participate in the project. We are mainly looking for effect related contributions. They are to be implemented in C in a somewhat limited environment . A Blender based simulator has been implemented to make it easier to visualize the algorithms.

In addition to elovalo.org, those interested should check out https://github.com/hacklab-jkl/elovalo .

The challenge deadline is fixed to 19.9 although it is appreciated that possible entries are delivered before so we have time to integrate them to the trunk. No prizes, sorry. Just fame and name in the credits.
