A useful tool.

This is a diceroller.

Nothign new, I know, but this is slightly different.  It's a simple HTML diceroller, with a twist - if you have multiple people using it, and they all put in the same password, everyone one with that password can see the dice - and you can also color the rolls as well, further seperating them. 

It was a pretty nifty tool.
