Metal Gear Gekko
This is the result of a good morning's worth of work. Ah, I love the Gekkos, I dare say they're cute, as walking tanks go :)
EDIT: There seems to some confusion about the scale. Guys, this is minifig scale. Compared to the other Metal Gears, the Gekkos are tiny little buggers.
And, of course, don't forget to check out the gallery.
