That's an awesome project. I'm sure there are many kids that have been gifted LEGO knockoffs that are not compatible with legos from adults that didn't know any better. A similar "interop" project for those would be great

Almost all (back then, I hear the clone quality is much higher now) were "compatible" but had little to no clutch power, a wall built with some of them would inevitably break at the clone bricks.

Crappy tolerance in the clone parts. I hear the clones got much better now.
