Useful for digital artists who want to use a photo reference with virtually any 3D package (ie zBrush, Silo, Blender, Messiah, etc). It only runs in windows, and seems to run better on an nVidia card... but the price is right: It is free. You can download the RAR at: http://www.digitalartistguild.com/misc/DAG_ForegroundUtility.rar
Poetic Lab's faceless Silo Clock uses lines and shadows to tell the time Designed as a "kinetic sculpture" that offers an alternative to conventional timepieces, Silo's line-drawn hands reference geometric forms. The hour and minute hand are each incomplete triangles, and as they turn with the passage of time, the shape they form together changes.
