Somehow I have lived the past few years without having ever heard of Food Replicator, a Star Trek-themed food blog. Especially noteworthy is the author's attention to the delicacies of Ferenginar, such as jellied gree-worms. Yummy!
Above you can see a gingerbread version of the standard Starfleet communicators used during the original series. Here's how the author made it:
I cut out the pattern pieces on thick card paper and then used that to cut out the cookie pieces. I froze the dough before cooking as this helps it keep its shape.
I used royal icing (1 egg white, add icing sugar until the desired consistency is reached) for all decorations, as well as for gluing the pieces together.
Toothpicks and scrunched up pieces of plastic wrap are both very useful to use as prop-ups while waiting for the royal icing to dry when gluing the pieces together.
