Last year they made me take down my interlocked RGB projector which was located at well above eye level and pointed at a wall, so I definitely won't be bringing it this year.

Laser classes are to give a quick impression of how to (not) look at it (pun intended). Class-1: Could be a friggin death-star inside, but everything is safely contained within the device. Class-2: Laser leaves the device but is eye safe even on direct exposure.
Yes, Class 1 and 2 are useful for consumer devices, but the class system is basically useless for devices *intended* to emit laser beams beyond a 1mW laser pointer.
