Okay, im very new to Blender (used it like 1 day). I got it like a week ago but all the buttons and panels and text that popped up scared the crap out of me so it tooko a week before i started.
Anyway, this is a normal cube that i extruded and when i was about to unselect the selected vertexes i slipped and accidentaly extruded it in some strange way up. I also extruded in a sort of hole in it, but it got very dark there so i added a lamp in there. After some simple subsurfing and texturing it looked pretty nice in the renderer. Added a UV-sphere that i subsurfed and textured, for me it looked pretty nice afterwards.
(I know i suck at this, but ive only used blender for like a day or two.)
