the reason i ask this is couse we r making a multitouch table (
http://www.multitouch.nl) (or search for jeff han in google) and we want to test how its the best way to lit it and i need to test if the cam is catching the reflection of the infrared lights so it would be cool if i could see the light sources in the reflection of a mirror. i try to lit the object and make something different but this isnt accurete since i cant limit the light cone of the object.
