Gear Gravtech is a small techdemo showcasing Gravity, within portal to later be an element within Gameplay. It was released in January of 2008, before Map Pack V2. Since then its been downloaded over 4,452 times, and still going! The techdemo is only a single, very small map meant and designed to simply showcase the effect, yet was later extended into a much large portion of a map within the New map pack. Before being updated, the player could spawn an endless supply of Weighted Storage Cube's, until Either Portal crashed, or their PC did. Because of that, it became very popular as a Stress Test for CPU's and Graphic Cards.
