I'm working with this fellow, and he's quite a pleasure to collaborate with! He did the graphics for everything on Plaid Notion (excepting a few well-hidden, very ugly old things of mine) and is quite skilled at animating (especially effects) in a wide variety of styles. Note that his skills are by now a cut ahead of the site's older games!
As an intermediate-level game programmer he's also quite equipped to communicate regarding technical matters--also very relevant to ingame animation. As an anecdote, he and I once spent several hours working with a particle animation to get it just right. We eventually settled on a carefully-tuned combination of pre-animated graphics and free particles which became the pixel blood in 'Lapratan V1'.
He did my avatar too!
Consider this a sparkling recommendation.
