Great news, I recently was invited to participate in the Graphic Artists Guild’s Illustration Directory iPad application. The app will create a digital, flippable portfolio of 5 images per artist and will be available sometime in April.

I have been wanting to get more involved with tablet technology, and this will be a great way to reach art directors and buyers who use the iPad on a regular basis.
