CSS Shadow Gradients Generator

A couple of days ago I was working on a new design and I came up with the idea of using a beautiful gradient shadow.

I went straight to Google and searched for a generator for shadows with gradient colors.

No results.

I thought. Ok, this is messed up! This MUST exist.

I had a quick dinner, I locked myself in my room and started it. I wanted to do something simple and quick. At 3am I had a working version.

The next day I beautified the interface and added a few more color combinations.

I thought it'd be a good idea to share it with the world before spending more time on it. So I'll wait to see the feedback and see if it deserves a domain by itself and a bit more of my attention.

Feel free to destroy it with your most honest feedback!
