What do you think this puzzle looks like?

I was playing around with some thermometers (the sudoku kind) about a week ago and came up with this puzzle. I couldn’t decide what to call it, since it doesn’t really look like anything (maybe a weird monster?). Cracking the Cryptic featured it yesterday, and they said it looked like tepees. In the comments, someone else thought it looked like a bunch of swords. What do you think?
