An old-Aperture-style science sphere for Valve's Portal 2 focused on the use of mobility gels.

This single-map test chamber features long-distance flirangs, steep drops, and puzzles centered around repulsion and propulsion gels.

It was created in two weeks for a mapping contest, and refined for another month afterward with improved visuals, puzzles, and bug fixes.
