I have a school project that involves building.engineering something, and I want to make a Rubik's cube mod. What are some cheap, easy mods that won't take much time?
I've tried designing a bump megaball, figuring that could be relatively easy to expand to giga/tera/peta, and it's not as simple as I first thought. I hadn't taken into account that the cuts converge, unlike a cube. It would actually be much easier to design it from scratch with relatively large centers.
I will give you my standard reply. Make something you have thought of yourself. That's far better than simply copying something already made. Deciding what should be based on materials available to you and your own talents.
