I have been drawing a lot on my new Wacom Intuos4. Last night I drew my usual panda character coding on his MacBook Pro. You can view the final painting on my Flickr. I also created iPhone and Android wallpapers out of it for myself since I have a G1 and a iPod Touch. I had people ask for them for their phones so I decide I will have them here to download.
I am considering doing more wallpapers if there is an interest. Let me know in the comments.
Update (Oct 14, 2011): I added higher resolution versions in a new post.
