Everybody is like "Ooooh it runs blender". It's kickstarter my dudes, these are promo renders. There is basically no information on the linked page other than "launching soon" (as in the kickstarter campaign is launching soon). So they probably haven't yet gotten anything to run on this (so we know nothing about the UI /OS if they modified anythinf / plan to do so, or basically anything at all...)
Their own website has a bit more info, including a demo video of it running debian. The primary focus of the project is the hardware itself, but the rasberry pi base means that there is a giant pool of available software already out there.
I mean. The RPI runs a fork of debian, and can definitely launch blender. It can't run it well and good luck using blender without a mouse, but i have 0 doubts that this thing can open a blender window.
They have an instagram account for conversations. This version only lasts 7hrs. I don’t think they are trying to revolutionize the world with this. You can see some of their other versions running. And since it’s open source I assume you can do whatever you want to it.
