Thanks app, those are nice 

I promise I'm not trying to one-up app.     

I know. In fact I think you made your set long before I made mine. If you recall, we both shared them with the same person in the DC IRC channel, shortly before NANY. 

I also have another number set, but they are only png, psd, psp (no ico), and were designed for web use (same CC-BY license):

They are a better remake of the ones I originally made for page numbering and navagation on my old art site.

Today we are glad to release gCons, a set of free all-purpose 32×32px icons for designers and web developers (100 icons). The icons come in 12 different colors and are available in PSD, PNG, JPG and GIF formats. This set was designed by Sarfraz Shoukat  especially for Smashing Magazine and its readers.

I've been using www.vectorstock.com for a while and buying vector art there. It's very cheap, as in $1 or $3 (some more). Which pretty much makes it a no-brainer for a lot of things.

I'd posted here about it:

There is a set in there that I've been using quite a bit, repeatedly. It's just simple glass buttons and letters, but it looks very nice and with a bit of editing effort, I've got an unlimited set of buttons.

They've got lots of icons as well, some better than others.

However, as it is vector art, you need to do some work with them, but it's worth it. I pretty much use PNGs whenever possible as they simply are far superior to BMPs or GIFs. You could make icons (ICOs) from the vector art, but I find that I rarely need ICO files.

Not free, but at $1? It's about as close as you can get.
