Talk about ROI! Eighteen months after Accel-KKR acquired Alias Systems for $57.5-million, it sold Alias to Autodesk for $182-million. That's a cool 300% return. Toronto-based Alias, which makes special effects software used for movies such as Terminator 2 and Jurassic Park, has been a hot potato in the past few years. Before Accel-KKR appeared on the scene in April 2004, it was owned by SGI. Alias has  sales of $83 million and 600 employees, mostly in Canada.
