Thanks for the link! I've seen an early alpha version of GP during the Scratch conference of 2016 (the 2017 conference is wrapping up tomorrow), and it worked awesomely, like a supercharged version of Scratch. A fun thing about it is that it features a very small VM, and the rest of the interface and blocks are written in GP itself, and can be readily inspected and modified.
