There exists only one superblock so far, and it is a prototype. It was created last month.
The hype is well ahead of the reality.
You can find plans for more superblocks, but the official website is mostly in Catalan only, so it might not be too helpful to you (assuming you don't speak Catalan)
Thank you very much for the info! I spent so much time searching in vain for these superblocks, but that was more than a month ago, so now it makes sense.
