Difficulties of integrating lightdraw with 2x3 tiles

Difficulties of the integration

-The brightness of the 2x3 is too bright. When the laser shine on the screen, the screen is brighter than the laser.

Attempted to solve the problem by changing the brightness, consulted Bernard and he said that we can't change the brightness.

- Logitech webcam too small, therefore we need to move towards the back of the room to capture the whole screen. 

- Cannot place the camera at the back because there are no space due to the projector racks and frame.
