Usually when someone comes up with a new building style they make one or two sample models to start and immediately put them on display on Flickr or some other photo sharing site or forum. Angus MacLane on the other hand made 101 different CubeDudes before he posted them!!
Just a little smaller than Miniland scale, but with larger heads these Chibi-like characters are definitely their own scale. If you are going to BrickCon, look for the ones that Angus is bringing there.
They are so cool and so cute, you just can’t help but want to make your own set of CubeDudes.
