Well, I've got 2 low power relays(can be turned on or off with the arduino), 2 phototransistors, Some LED's, Some 20K resistors, Some 200 ohm resistors, and a laser.
Any ideas?

Hmmm...I would need a higher power relay for the lighting part...

I would still go with something about laser trip wire.  Got a piezo buzzer or speaker laying around? :)

Got a buzzer...Hmmm...But I don't have any cable...At least any more than 2 ft

laser tripwire that has a sexy voice saying hello when you walk in

and what? no wire?

go to the home improvement store, they sell it in all flavors fairly cheap

Another lazer tripwire? I can't do that. >_< I don't have enough cable.

ok ok fine no wire ...

try beaming a serial signal across the room using the laser

What do you mean beaming a signal?

hook up the laser to an output and see if you can ReCreate* the signal on the other side using your phototransistors

*eh eh! bad pun on your name, ++props  :-?

I assume Osgeld is referring to a morse-code type of communication that sends messages by flashing on/off the laser and receiving it on the diode.  I'm pretty sure I've seen someone (Make Magazine, perhaps?) doing this just by hooking up the laser to the TX pin, and then hooking the photodiode to the RX pin, and using serialPrint() and serialRead().

Osgeld

course you could just do a laser tripwire by putting batteries on the laser and the arduino as the receiver

::)

Hmmm...Like a data transfer link? Hmmm...
