First of all, just want to say, Merk Vilson is a genius and releases stuff very frequently on Patreon (not just Topoformer). He has a ton of really useful plugins, tips, and tutorials he releases all the time. I've been using Cinema for about 8 years and he's teaching me a lot. So, if TopoFormer doesn't work out for ya, you should still definitely get your money's worth. Also, I think they only charge you on the first of each month, so if you were really unhappy, I think you could back out if you remove your pledge before April 1.
As far as Topoformer, I'm not sure what you're able to see on Patreon without being a Patron. Here are some links showing various functionality:
He also has a random polygon selector plugin which you can get without being a Patron: https://www.patreon.com/posts/random-poly-16743615
