So I'm relatively new to Bitcoin, and I was quite confused as to what a miner actually does, what the difficulty relates to, and so on. I decided to put a quick site together to demonstrate what is meant by the "target", and how a block is regarded as "found" relative to the target.

I called it the obvious, Bitcoin Target: http://btctarget.com/

Check it out, let me know what you think, and particularly let me know if it breaks or falls over. Thanks!
