The Powder Toy

Matter (opposite)

All of your computer's text is replaced permanently with hexadecimal ASCII codes.   I wish for a beluga whale.

It is in the far future, where the nuclear material has decayed and was removed,   The next user is in the caveman times, where a nuke explodes above your head. You only have caveman technology.

Granted. You sleep in and get fired/late slip. Since you were trying for the employee of the month/perfect attendance award, you commit suicide.   I wish I had a beluga whale.

Dirty (opposite of clean)

Ehole has a 1500 particle overlap limit, while normal particles have a 5 particle limit. I find that annoying at times.

Would sound cool! 

Interesting... I think this can be done if each particle uses its vx and vy values separately, much like phot does. My only concern is the angles, as trigonometric functions don't always give in...

cleaner (vaccum cleaner)

I found out if you type 91.121.227.69 into the address bar of internet on a school computer, it will directly connect to powder toy's server, bypassing any block implemented.
