Scribe's Scratches

Well there's the slideshow, didn't upload like it was on the smart software and I tried in 5 different formats...
If you want some more practice I attempted to make an applet in JAVA. I must say it's one of the ugliest computer programs I've ever made and it was a heck of a time making it work online (even though it is still sketchy even now seems to work all the time on ei6 and from time to time completely kill firefox). For any computer programmer people out there who look at my code I know it could have been done better with arrays but I remembered that JAVA arrays were kinda funky compared to VB so I didn't bother re-reading that part of my book and just avoided it. Here is the program (hopefully) the code is under it for anyone else who wants to compile and use it (but I doubt it). I'll try to make a smoother, better looking, more complete(more angles) and more stable program some other time. I didn't this time because there are just too many little things that went wrong. Spent an hour debugging and the bug was a single equals sign. ugh.
