I should start out by saying that this is not my idea, it comes from a guy by the name of sWooZie, a while back he posted a video of a pretty awesome sculpture of Ryu from Street Fighter and after looking through his videos, I found this guide on how to make one, and I thought that I was up to the task.
So far I've made multiple sculptures, Ness, Megman, and a 1-UP mushroom.
Before we get into things, I'd like to thank sWooZie for giving me permission to write this up.
Basically, what we will be doing is cutting up some timber into squares, these squares will then be painted and act as individual pixels in your sculpture. I know some of you will ask, "Why not just get a plain slab of timber and draw a grid on it?" the answer is, that doesn't give the same effect and it also makes painting a giant pain. This method gives you a very nice finished product. You're looking at about 2 - 3 days of hard work to finish this, I did mine over a week, very relaxed like.
