You can find knock-offs all over the web and places like Alibaba. This one was pointed out on Reddit recently and I ordered a couple, but shipping will likely take a while. Also note that they seem to be backordered now:
That's really neat that they give instructions on how to build your own, but I kind of want a way to just buy it and get the product (as shown in the animated hero) delivered to me.
