Where can I find a good Number Randomizer on the Net?

[Anyong]

Where can I find a simple number randomizer that randomly generates numbers between 1-28 that is free to download and store on my desktop.
Good websites please!
Thanks for suggestions, but still not content! I need a generator to download and keep on desktop at leisure - a zip file maybe?
More websites/ suggestions please!

Random.org has lots of free randomizing tools.

n = int(rnd * 28) + 1

Throw this into any basic compiler.
