Img28 (Windows 7)

img28 is a wallpaper included in Windows 7 as part of the Scenes theme. It was illustrated by freelance illustrator Adhemas Batista, whom Microsoft found on agency 72 and Sunny. It depicts various abstract shapes in mostly shades of red over a dark purple background. According to the artist, it represents "universe that [features] many unknown forms as a colorful representation of the vastness of space".

Adhemas Batista also designed the user account picture Usertile19 (Windows 7), which depicts a similarly-drawn striped marble.
