I am helping Jason out with an LED build that may interest a lot of Profilux owners out there.
This build is a massive undertaking and features a significant number of LED's all controlled via Profilux for incredible simulation options. 200+ LED's all arranged in a pattern that will allow for left to right style diming, sunrise/sunset etc.
Here is a link to the build thread, worth a look for fellow DIY'ers.
