I can't remember where I found it, but there's an excel spreadsheet that you can download. I find it very useful for figuring out the greeks on real as well as imagined options. It's especially good when you want to predict an option price by varying the underlying price.
If you just want to look at the greeks outside of Excel, go to the Option Industry Council site, http://www.optionseducation.org/ Hope this stuff helps. BodyworkeR
