Ice cube trays in the form of R2-D2 (who cares) and Han Solo Frozen In Fuckin' Carbonite (frozen in fuckin carbonite!)! Get your Jim "Laser" Beam on the way it was meant to: With Han Solo just chillin' (HA!) in your glass. Available soon wherever stuff like this is sold.
Also suitable for chocolate, if you're into that kind of thing.
