Most self-portraits are, by definition, solo affairs. However, artists Alon Chitayat and Rosalie Yu are blurring those lines a bit. Their Skin Deep art installation lets you draw on 3D-scanned models of the creators, giving their self-portraits your own creative spin. You don't even need any special tools -- all you do is doodle on specially marked paper, and webcams translate the relevant sections to textures. While you sadly won't have an easy time trying Skin Deep yourself (it was made as part of New York University's Interactive Telecommunications Program), it's easy to see the underlying concept applying elsewhere. You could see games where players personalize their characters, or 3D painting programs where real-world art adds some flair to digital masterpieces.
