A group of researchers has developed a solution: 3D print a lithophane, a thin plastic sheet that displays visual data in the form of bumps and other surface features.

For a stained protein or nucleic acid gel, a lithophane can represent the intensities of the stain as variations in relief. 3D printers have become widely available, and the printing only takes minutes.

If I can get a lithophane system, then they can just print out their data for me and we can be talking about the same piece of information at the same time.

But if she knows what diagrams she’s going to do before a presentation and prints a lithophane, problem solved.

So for like a week I thought we had invented the lithophane.
