Just a Lego model I finished back in January. The project took me about a year to complete though (I'm a slowpoke).

The design concept was sort of a serpent dragon crossed with a jet plane, hence the jet engines and tail fins. I imagine Zetta being some kind of supercomputer ("Zetta" being derived from zettabyte) collecting data from worldwide databases. Or something like that; I'm no good at characterization. :P
