Are you an avid collector of all things Lego?

Are you an avid collector of all things Lego? Are you a fan of science, or perhaps just a fan of genius in general? Maybe you’re just a collector of very odd esoterica and like to show off all the weird stuff you have? If you fall into any of these categories, then Amazon seller The Living Brick has just the item for you: A Stephen Hawking Lego kit.

The item, which is selling on Amazon for $39.99, comes complete with every piece you’ll need to recreate the venerable physicist, as well as a detailed instruction manual — you know, in case you aren’t the Stephen Hawking of Lego-building and need some guidance. Only 100 of the kits were made, and according to the Amazon page as of this writing, only eight remain. The kit comes with brand-new parts, and ones that are official Lego bricks, rather than some knock-off brand.

Checking some of the product reviews, there are reports of the finished model being a little flimsy, with pieces not being sturdy enough to stay together. However sturdy the model is, it’s actually quite impressive that some small, solid-color Lego pieces were able to represent something so complex and make it instantly recognizable.
