Created a massive character sheet for fun.
The general idea is that once you have images commissioned or generated you put them into place, fill it out, and then print it up as a placemat sized banner. 3 feet wide by 1.7 feet high. 36 inches wide by 20 inches tall.
You can roll it up like a scroll (with the key info in the middle, and secondary on the sides). It becomes its own dice mat, as well.
I get weird ideas when it rains.
