thats a good list of stuff u can do with a laser pointer... the pointer itself is somewhat like an LED, but the molecules are concentrater differently as to give a thinner more concentrated light ( laser dot) rather than a distributed light as with an LED
It's not that similar to a LED, best page I could find in a few mins:
