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.

    they sure don't look the right size :P mynanoblock.com/site/wp-content/uploads/2010/11/slide-11.jpg Edit... oh wait that's the "mini" series Oct 25, 2011 at 21:03
  • No, that's what I'm asking about. They appear about the same size as Modulex (although I've never used Modulex), and AFOL are a creative bunch - I wouldn't be surprised if someone figured out a way to integrate them with regular LEGO bricks as well.

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.

    Obviously they aren't going to fit right on top of a LEGO stud. But the question is about generally compatibility - for example, are they compatible with Diablock (for which there are LEGO-compatible adapters)? Are they compatible with Modulex, which is a Lego Group product incompatible with standard LEGO bricks but at the same scale? Are there any LEGO pieces which will serve as a hacky adapter?

I can attest that Nano bloks (left) are not the same scale as Modulex (right).Nano blok and Modulex
