We took a PS3 camera, hacked it open, mounted it to an LED light, and now there's a device that is free, you build this yourself, we publish the code for free, you download the software for free.
Tomamos una cámara PS3, la abrimos, la montamos sobre una luz de LED y ahora hay un dispositivo que es gratis -lo construye uno mismo; publicamos el código gratis- el software se baja en forma gratuita.
