Can I build a Dynamicland clone in my area? That'd be excellent. For all the press this thing gets (from time to time), I still see neither designs, plans, nor code that I can use. Is this because Bret Victor shares ideas and expects that if the world finds them valuable, they'll implement their own? Or is there another motivation to hold this close? Maybe someone has to build an Open competitor so that we can address problems mentioned by other commenters. Maybe I'll do that here in my hometown and share it with everyone.
