Spaceman Spiff

Spaceman Spiff is an imaginary hero of Calvin, by Bill Watterson.

I've modelled this Spiff for one of my graduate mentors, Klaas Jan de Kraker, for attaining his PhD degree.
His PhD thesis is about feature conversion for concurrent engineering, and he and Maurice made a prototype multiple feature-view modeling system called Spiff. Spiff stands for System for Product modeling by Interaction on Form Features, but the name appears to have a secret relation with the famous Spaceman Spiff, interplanetary explorer extraordinaire, hence this model.

Spaceman Spiff is modelled over an iron wire skeleton with aluminium foil. He stands on a feature model with a piece of styrofoam as a base. See course for details about how it was made.
