This is a quick game I whipped together. Read the license carefully. Don't hurt anyone with it. Its a high frequency noise maker perfect for all the pranksters out there... It has five frequency generations, each are around 3 seconds long, synthesized by me, and range in Hertz from 7000 (low) to 18000 (very high). Don't be stupid and use this on a real animal... Just use it as a prank/joke and be careful. The dimensions are formatted to run on a Sony PSP, thus making this portable, I'll release a downloadable one sometime in the near future and instructions for transferring it to a PSP. If you have any other mobile devices, give me the measurements of the screen and I'll be happy to make a version for it.
