Just gave it a test run. A fun little program, easy to use,lots of predefined brushes, even speaks my native tongue (Danish). Guess it would be OK for simple drawing tasks, especially if you had a digitizer (don't know if it is supported?). The pictures, however, can't be saved or exported - they are stored within the program (I have looked through the different tuxpaint folders, but can't seem to find them). According to the readme.txt this is supposed to be this way, so that kids, using the program, won't be able to screw up the computer
