Sorry for the prank. Have PlasmaDoodle

[STxAxTIC]

This program captures whatever you had on screen at the time of launch, and then draws it to make a "clear" window.

If you don't like where the window started, you can move it and press SPACE to re-center.

After that, click & drag anywhere.

Well I am sorry for calling it a prank, because I could not figure a elegant way of escaping or preventing code from getting stuck in full screen.

It does make a pretty clever one! Perhaps I gave you too much credit :)

Nah man, it *was* a prank :-)

Protip: load in full screen, then color the bottom corner of the monitor as if it's been dropped....... and then just leave it for someone to find.
