Are Nanoblocks compatible with other building bricks? Recently I have found Nanoblocks, a Japanese brick toy, in American stores. How compatible are these with other building toys? They look to be approximately the same scale as Modulex.
It appears that the goal of the nanoblock producers is to make "the world’s smallest toy building blocks"1.  And they appear to be too small to be compatible with LEGO.  See the following video comparisons of the sizes.
