Twitterkeys is a great little collection of symbols and shapes that are UTF8 compatible. This just means that these shapes can go lots of places a font-based (dingbats) or html dependent picture (.jpgs and .gifs) can't go.
Originally made by TheNextWeb for enhancing Twitter posts, I've found this bookmarklet helpful for spicing up my communication in other places, like forums and email signatures. Just drag this link to your bookmarks toolbar: TwitterKeys and you've got a pallet of very portable symbols and glyphs at your copy & paste disposal.
