Since I have a solid black background, I decided I needed to make up an icon that I can see. So I put together a quickie effort for myself and figured I'd share it with y'all in case any of you like it. I know glassy buttons are as trite as you get, but I always wanted to try making one.

Since it appears that there are no attachments allowed in these forums, I put it up on a web page with a sample image showing what it looks like.

(Unless Alex wants to use it, in which case I'd make an exception, I'm not intending to improve upon it. It does the job.)
Enjoy,
Greg
