Craig Newman made an application for a multinational retailer that controls 80 LED's set into Strass crystals that are mounted onto a large pink wooden display in their stores. The app is essentially a console that allows the user to set patterns, rates and dimming levels among the LED's, creating choreographed scenes that are stored internally. These may be played back as desired in any combination.
The application communicates with the external world via a USB interface device that takes LiveCode commands and translates them into both digital and pulse width modulated waveforms. The output of the device connects to drivers that power the LED's.
Some of the displays are in Muslim countries, and the application turns the display off at preset prayer times during the day.
