So you'll have to settle for photos of cake.
Since Zoodle isn't old enough to care what his cake looks like, I chose the theme. The Engineer and I are huge fans of the Sci-Fi Channel series Battlestar Galactica (the new one, not the old one!) On the cake I tried to replicate BSG dog tags (see what they really look like here), with Zoodle's birthday as the serial number. BSG splits each season in two--season 1.0, season 1.5, etc. So instead of "Happy First Birthday" I wrote "Season 1.0 Wrap Party." (On these photos I edited out Zoodle's real name.)
I can only hope that when he's old enough to choose his own cake theme, Zoodle turns out to be just as much of a geek as both of his parents are.
Happy birthday, my sweet little man!
