MythBusters star Grant Imahara unexpectedly died on Monday, with sources indicating that he suffered a sudden brain aneurysm while at home. The news understandably shocked and dismayed fans of his work, which goes way beyond what we saw on Mythbusters. In addition to his work there (and on related show White Rabbit Project), he was a trained engineer and roboticist, working for ILM on animatronics for major movies, with his projects featuring in The Matrix Reloaded and Revolutions, The Lost World: Jurassic Park, Terminator 3: Rise of the Machines and Star Wars: Attack of the Clones (where he was responsible for R2-D2).
