Hi guys, I'm trying to do a grid that rolls up in sop with vex but with no result at the moment. I was wondering if anyone knows something to begin with. I thought about matrices that drive the rotation of every row of the grid in sequence from left to right in the x-axis, but I didn't get a result and maybe this is the wrong way to do it.  If someone has an idea I really appreciate. Thanks! ps. I hope I have been clear enough and didn't make too many writing mistakes.
