A stool that spawns a lamp/light (if you can do both left click = lamp right click = light etc.) using a strobe effect, if you can, make it so you can adjust the speed of the strobe light, and the size the lamp will project, and the brightness and size the light will give out.
Someone please do this?
Edit: Going away for the weekend.
Hopefully you guys will have done it by then, or continue doing whatever.
