How could they possibly fit a 4-port USB hub into a LEGO brick? They used one of those DUPLO bricks—you know, the anti-choking kind made for toddlers or whatever.
Luckily, this hub isn't just some 20-step Instructables idea that you'll never do. You can actually buy this thing in one of seven different colors. Sure, it'll cost you $50 and an extra $11 to ship—or about 2000x what you can find a USB hub for today. But your kid won't haphazardly yank just any USB hub from your desk, taking your precious attached storage to the floor with a crash. [Etsy via OhGizmo!]
