Last month, I did a series of iPad-friendly illustrations for the HHMI Bulletin with the overly-talented Jennifer Lee over at VSA Partners.
The article dealt with bones and the team had the nifty idea to do a series of illustrations where, when you pressed an icon, an x-ray version of the image would be shown.
A subscription to HHMI is free and so is the app! If you're a fan of illustration, they feature a lot of the greats. So now you don't have any excuses and you're obligated to check it out.
