Ideas for a computer project. Update, began to work, need someone to test. [using computer science] [math competitions]
Q: I plan on introducing a single science / math competitions next year and want to do with a Computer Science. The language I would use will or C + +, + + VC. NET managed code, or VC #. The games I plan on entering the Siemens Foundation, LISEF, and a few others. I want a good project to do, but Im pulling blank on ideas. So far I have thought about a couple, including anything to do with encryption, or something to do with compression. For the compression and encryption, Ive never made a program that encryption (Im not sure the algorithms can not yet do), and Ive only done a trivial encryption programs (ASCII shift, and one using a matrix that a key is stored). Does anyone have any idea for a good project, or ideas on how I can expand on those that I have? If so, do you have any good links? Thanks for the help.

Thanks for the link guy. I just started working, and was wondering if someone would try to crack this for me. I just created my own encryption algorithm, and want to see how it works. I will post the output from putting a string in, and see if anyone can get the original string. Here it is:
Ço0?⌐lcb|n⌐lR▬~╪
This was created by sending in a string to the algorithm (will do files later). Can anyone who has the time, or the knowledge please try to crack this. I am hoping that it is fairly strong. If you can crack it, can you tell me how long it took? Thanks.
I really don't think it's possible to get the plaintext from that, even if you use a simple cipher it's pretty hard to decrypt a few characters.
EDIT. If I were you then I would do something like a multi-object gravity simulation. You could do some fancy graphics with it then as well 
Re:Write a jpeg decoder…. That lossy compression is confusing as hell.
Re:not me
Way out of my league, but here's a bump for you.Re:Bump. I really want to see if this algorithm is as secure as I theorize. I believe that there are at least 255! different ways that the same input can be output (depending on certain factors set by the user). Can anyone attempt to crack that little string?

Re:A cryptography link (http://www.infosyssec.org/infosyssec/cry1.htm)
You could write a program that does stenography(hiding data within a file) with Divx movies. I chose Divx, because I frequently download movies in that format that are corrupted in certain areas (the video will start to go crazy, change colors, etc), and I'll just go and download another version without giving it a second thought. This is good, because stenography usually will alter the original file so that it looks a little strange, but when you are using files that are commonly corrupted like Divx vids most people will just assume that it is just a bad file and ignore it.
Re:Bump, anyone have any ideas? I am leaning towards encryption, but need some guidance (ie links, I can't find any really meaningful links on my own).
