I just discovered this online DSLR simulator, I don't know if it's been posted already on this forum but here's the link:

I thought it was fun, and something beginners (like myself) could make some use of. I still have to practice a lot because it takes me a lot of tries to get the settings right before taking a photo. It's nothing like the real thing, but it does give a pretty good idea for settings combinations I think.
Cheers
