GTA4 style phone for a CS?

[Statyk]

It wasn't being rude. It was being short and to the point. There's no sense in building on an explanation that doesn't exist, therefore, saying "You can't." couldn't have been an easier answer. Though right handed lightsources would require 3D modelling and custom animations to replace, it IS possible... But a complete waste of time, no offense.

In my opinion, I don't see how this would be useful at all anyway...

I don't ever see YC being rude. Just stern and answering in a fashion that gets the job done. Don't take it personally.
