Thank you for the lovely comments, folks! Much appreciated. I'm sorry that the icons don't come any bigger, sbk, they are designed to be this size. I wish I could sort out the resolution/sharpness though as some of them are a little blurry when I gather them together like this to post them.
Let me add my compliments, these are great.
Uh...you DO understand I plan on stealing them, right?
Just don't be surprised if you see them in use around here sometime soon.
