He also did the technology behind the visual effects, including the beam effects, tracers, sparks, lenticular halos, decals, and fog effects.[6][4] He worked on the physics engine of Half-Life 2,[7] and was a project lead on the Xbox version of the game.[8]

Stelly's surname appears in Half-Life as an Easter egg in the Anomalous Materials laboratory on a locker. His face is also used for the obsolete entities in the level editor, Hammer.
