Possible Diorama Buildings...

That looks very close to HO scale certainly not PlaKid scale but then they aren't to scale for Plarail trains. It looks like an HO figure would look good standing at the Museum entrance. May I ask who makes these buildings?

It appears to be some brand of bricks that emulates the Lego bricks design, which there are numerous companies that do. I've also seen bricks that light up on their own with no need for an external electrical connection from the brick as the baseplate the bricks are placed upon provides a wireless connection to the bricks above it. Youtube user Jangbricks made a video on them a while back.



Very cool innovation in my opinion; it gives you more freedom with what you build.
