Send a less ordinary greeting card this year with your Merry Christmas message in secret binary code with decoder. Single cards or packs available.
We've used ASCII code to create these secret message binary cards, each with their own decoder key on the back. This one simply says 'Merry Christmas' in a lovely Christmas red colour. Perfect card for geeks, or anyone really because who doesn't love binary humour?!
Our range of Christmas cards come as singles or in packs of three or five identical cards.
We have more science-themed Christmas greeting cards available in the Newton and the Apple shop.
Our Christmas card designs are printed in the UK on premium matt 350 GSM luxury card. The inside of the greeting card is left blank for you to write your own message.
Christmas card measures 10.5 x 15 cm when folded.
