It’s our Make: Online pal Sean Ragan’s birthday today, and look what his mom made him: a chocolate retro birthday computer! When I inquired as to how it was made, Sean replied:

It’s cast in a couple of molds. Apparently the trick is “tempering” it correctly to avoid a dull chalk surface. She has a non-contact IR thermometer that she uses to get it just right.
