I guess that this is a kinda spiral pyramid judging from the contour lines. Or is it a concave/convex face structure or are the top and bottom faces flat and right and left faces concave. I think the latter but with a truncated top. Or else the top is a ridge running right/left and not shown as it is lower than the next contour line above the smiley face. Its definately not a point which is the point of the thread? is it not!
Don't be sad Elmo, we have all seen your brilliant work at multiple duplications of some mighty fine contours that end with an (unseen) point! They sure are mighty pretty.
