Yes, that's Han Solo encased in carbonite--and he's made of Lego! TechEBlog has posted "The Top Ten Strangest Lego Creations", but IMHO, most of them are pretty cool, from an iPod case to a harpsicord to a (working?) knitting machine.
I never really got past making a dog from the stuff myself (two pieces)--and if I had this much free time to concoct something so epic I'd probably devote that concentration and mechanical prowess to building irrigation systems for starving villages or something. Who knows, maybe this is just a warmup to the next big thing, after all, our last Great Hope--"Ginger"-- turned out to be nothing but a scooter...
