Img23 (Windows 7)

img23 is a wallpaper included in Windows 7 as part of the Characters theme. It was illustrated by freelance illustrator and stop-motion animator Chris Sickels, of Red Nose Studios, whom Microsoft found on agency 72 and Sunny. It depicts a clay character flying over a miniature town square fountain, by agitating large feathers, while being watched by pigeons.

The objective, according to the artist, was to "create an image that conveyed adventure, delight, lightheartedness, and something fun to look at". He describes the scene in these words: "With his homemade cloud suit and a pair of feathers he takes a leap of faith at the center fountain where all wishes are made". He recalls the wallpaper was "a blast to work on" and even ended up using the rejected sketches for his later projects. Early concept art submitted to Microsoft involved the character flying using actual wings, a plane, or riding an elephant.

Chris Sickels also designed the Windows Live Messenger 2011 and 2012 scene Bird Man, which features edited parts of img23.
