CMYK T-shirts

I think that these t-shirt designs are pretty cool, although anyone that isn't a graphic designer would be left scratching their heads. I found these when searching for CMYK on the internet, and found a company SupremeBeing that have an entire range of CMYK themed clothing! They have even created characters for each respective letter-the second t-shirt here shows them. Basically, I want these t-shirts, but they are all about £25 each! I love CMYK, but not THAT much!
