Write a program to create random “songs” using Sounds. There should be a 9/10 chance of the next note being a note close in pitch to the previous one, but a 1/10 chance of the next note being very different in pitch from the previous note.
Modify your program to save the song in any format you choose. For a little more of a challenge, try encrypting the file save. Your program should also be able to open saved files. (HINT! Some Classes you need are: Sounds, Math, and File)
Advanced Challenge 1
Make a connect four game. Before the game starts, your program should give you the option of playing a person or the computer, and choose which color you want (just for a little more challenge). If you don’t know what Connect-4 is, read this wikipedia thing: http://en.wikipedia.org/wiki/Connect_Four
