"Man of Steel" (Superman) logo
This was 100% scratch-built from wood. 7-layers total, 29-inches wide
and roughly 15lbs. Sits snuggly in a scratch-built rotating base made of
an ABS-coupling, particle-board and a Lazy-Susan bearing-assembly.  
This allows the logo to be turned to display either side.
