I hope more people support this project. Not only because lowering the barriers for Processing programming is an exciting thing to do but also because this could be repurposed for other languages (the code will be released under GPL). Full disclosure: I'm an advisor on the project.

I agree. Visual programming has always been an interest of mine. I see physical parallels in the maker/electronics world and wonder why it has never seemed to spark in the code ___domain. Don't know if it will help, but I sent a message offering support/expertise (would offer $ had I any...)

Have you ever heard of Tango? http://www.witango.com/products/studio

Which maker/electronics projects do you see as similar? Arduino?

This reminds me of something created for the demo scene a while back: http://www.theprodukkt.com/theprodukkt

theprodukkt was a tool that the artist used to procedurally generate the 2D art for a 3D scene. A list of instructions compresses much smaller than a picture does, so they were able to create amazing demos in a really small size.

Unfortunately, theprodukkt just kind of fizzled after that. I expected to see that idea really take off.

This project is a great way to introduce designers and artists to programming. Processing is great but requires a lot of overhead to get started. DesignBlocks simplifies the commands and makes coding more intuitive, especially for visual projects.
