PYPoison

PYPoison is a relatively simple app which gives you multiple ways to terrorize your victim. It is completely safe, yet dangerously hilarious; your victim must endure a very annoying flash animation (of your choosing).

Said flash animation doesn't enjoy being closed. Your victim just has to quit the process, and everything is back to normal.
What's new in this version:
Added new Icon, readme.txt, license.txt, and a script to exit the application.
