Something to have fun with!

If you’re a fan of Pollock, the circa 2000 movie starring Ed Harris as the painter Jackson Pollock, you’ll have a ball being an abstract expressionist on this site. Just move your mouse or Wacom stylus around to create your own digital painting.
You can print out what you do, or you can save it by doing a screen capture if you have Photoshop or Photoshop Elements. In Windows, choose Print Screen SysRq. Then open Photoshop and select New document. It will automatically open the right size file for you. Finally, press Control V to paste in your painting.
I don’t have a Mac, but there’s a tutorial here that will explain how you can do a screen capture using that operating system.
What I did was Invert my original (the top painting) and then apply a gradient to the flower area to spiff it up a bit (bottom). Be warned though. Pretending to be Jackson Pollock is addictive! I could have happily spent the whole day playing with this.
