Brand Union Logo

I haven't found a logo I like in a while, but this one is very clever - the way they've used negative space is pretty great. They're an identity design company, so I guess having a good logo and identity is pretty essential. No idea who did the actual designing though, it's a global company, which makes it tricky. But yes, a very clever logo, the way the colours can be changed and such is nice too - they have a little animation on their homepage. Which is here: http://www.thebrandunion.com/
