Alright, no controversial post today. Instead, something a little more interesting.
Do you want to sculpt, but don't want to make mess with clay and also you have really terrible art skill? Also, are you a cheapskate?
If so, I highly recommend this program. It's tremendously easy to use, and even a complete amateur like me is able to find amusement in crafting some hideous monstrosity in mere minutes with its assistance. Give it a shot!
