I have a C program which plots the images. It's not really feasible to post it here, though. (Can the Web site maintainers hack their scripts to accept line-break and paragraph-break tags?) The big image in message 3 seems to be a solar system -- large sun, small planet, two medium planets, and three large planets. In that order. I think the end of message 3 is planetary descriptions, but I can't make anything of it. The last line is G 0 P o (image of six-limbed critter) o P 0 G, so I'm guessing that 0 (zero) is "Tau- Cetian".
