I recently discovered the work of Walter Allner via a post over on Aqua Velvet. Shapes, color, oh my. Genius. I'm probably way behind on the who's who of the designer world but that's ok.
You can learn more about him on RIT Graphic Design Archive.
And don't you just love this quote, "Raise the aesthetic standard — the public is more perceptive than you think.” –Walter Allner
