I’d like to tell you about Network Osaka, the designer of the posters you see above, but unfortunately they don’t give much information about himself (I’m guessing it’s a dude). What I can tell you is how talented he is. The guy is a master of all things type and shape, creating wonderfully colored designs that are contemporary and kinda futuristic at the same time. The way he uses abstract shapes is so subtle and simple but overall is really effective and making his work seem so interesting.
I’d also suggest checking out his Flickr, which to me seems a bit easier to navigate then his personal site.
