This lets you control mouse motion (mouse clicks just added!) with an everyday $1 laser pointer from up to 20 feet away (and way, way further if you have a more powerful laser).

All cheapo dollar store laser pointers are perfectly safe - just use caution on any laser you need to wear "lasershades" for.
