(sum 0 to N Mode) + Moldable = Modeable.
The most notable (modeable) example is Dustin Hoffman's teeth in the movie Hook. If you're confused, ask yourself, "How do they make Dustin's teeth look so real, with the gapping and disgusting yellow tint?" and you'll get this word as the answer.
Dustin: Simply because of Modeable Imagery--a new technique being implemented, especially for special effects in movies.
Hoffman: Splash idea!
