After reading this post, http://www.java-gaming.org/forums/index.php?topic=14439.0 I got a little inspired, and wondered if, {Maybe could I write a program to make a spider walk around randomly on the screen?} Of course I had too much going on and I traded in a spider with fully articulated legs and all for a simple ghost. Try it out, though. (And I know that anybody could easily 1UP me on this but I’m proud that this only took me about an hour.)
More versions to come! 
Note: because the forums will not allow uploading of jar files, I have uploaded it as a text file. Download the text file, then go into Notepad and save it as Ghost.jar. Double-click the jar file to get it going. If you want the ghost to go away at any time, just click on it.
