After making my latest Iron Man wallpaper(s), I had to find a good use for the older reactor designs. I decided to put them to good use as dock icons. They're detailed, so they don't work very well as small icons. Dock or desktop use makes the most sense, but feel free to use them at any size.
Pack includes 256px PNGs and ICOs from 256px down to 16px.
