Please note this is not yet the final product, expect bugs.
Instructions: This applet is much simpler than I would like. Just click with button one on either of the two sprites to move it about. The move process is slow as a result of being hacked together after my animatesprites fell through. To ditermine alpha channel of a pixel click on that pixel using the second mouse button. There is full alpha support but no obvious test case.
Known Bugs: Sorry about this but this refuses to run even in JDK1.1 enabled netscape. It does work using appletviewer remotely. try:
