nah, really just the current based stuff
some interesting use of lava too
and one where the loot falls on a switch which lets you know you have loot :)
Hmm, yeah, there is something odd looking about that bit.
But the're no slants in the game (notch said he'll never implement diagonal/smoothing blocks) and the vanishing points do match up, so it must just be Xen being at a funny angle, plus the dark stripe blending into the lower block, to make it look wrong.
