One of the many things I enjoy doing when I'm not working myself to death is baking cakes. This summer I've had occasion to bake two thoroughly geeky cakes.
The first occasion was a small party that I had with a few fellow students, to celebrate the fact that we didn't take incompletes in a notoriously difficult phonetics course:

The cake itself was a chocolate layer cake, and the frostings were: chocolate buttercream, white chocolate buttercream, and a mixture of the two (for the lighter brown).
And yes, that hideous decorating job
is an attempt at a spectrogram. I actually recorded myself saying the word "done" (in a frame sentence, no less), looked at the spectrogram in praat, and then tried to replicate that on the cake. All I can say is that I somehow managed to avoid getting frosting on my laptop in the process.
The second cake was in honor of a friend's birthday, and was a lolcake:

The cake itself was a yellow cake, with vanilla buttercream frosting (and a bit of chocolate buttercream from the previous cake, plus a few strawberries).
For the kitty pidgin on the cake, i opened with the classic
o hai greeting, followed by the familiar
i iz [food] trope, and then the classic
can has construction. Finally, the assertion
srsly.
Both cakes were very tasty.
