Mark Collen is a Seattle artist and animator who has been involved with Photoshop since its inception. 
His work appears on all of Adobe's Photoshop CD-ROM's to date, and has been exhibited by Adobe, 
Apple, Kodak, et al. domestically and abroad. The computer is his native art tool.

He presently works in 3-D animation for games, and Photoshop figures heavily in his daily workflow. He 
is also lead guitar player and singer for Two-Tone Tomcat, a Seattle electric-blues band, and lives in a 
Pioneer Square loft with a very smart cat. He will be 39 for the fourth time this year, and is incredibly 
deadly with a grenade launcher.
