I was fooling around trying out some different techniques for gradients for a level I'm working on. None of these were really what I was going for, but I figured someone else might be able to use them (or even just get inspired by them).

If you want to use any of them for something else, please ask -- I'll almost certainly say yes, I mostly want to know what's being done with it. For commercial uses, definitely ask first, and use only after I give permission, thanks. (Yes, that was basically a Creative Commons license in plain English.)
