That would make more sense to boast about if they weren't, for the most part (entirely?), collecting existing icons and assigning groups of nouns to them.

Also, many of their choices are rather less than international. A No-P no-parking icon? "<3" for love? Really?

Otherwise, a fair little resource if you want a very standard icon in vector format. (Mind, you apparently have to download and decompress each one separately - I found no links for a collection.)
