Artist who created the avatars?

Who is the artist who created the NP avatars. They have so much character and uniqueness to each one. The are really great.

You can see some old NP1 avatars here.

I am able to recognize some of the NP2 Premium avatars as being from the IHG game Jupiter’s Folly , which was written in Adobe Flash.

I am sure that @Jaykyburz could have an interesting story about who drew the NP2 avatars.
