As your child grows, it’s fun to track their development on a growth chart. Kids love to see the progress they’ve made from one year to the next and this chart, found on a tumblr blog, is better than most. You can track your child’s growth from tribble to dark lord (or somewhere in between). The chart encompasses four franchises that are important in a geek’s growth and also provides perspective on the size of some of the characters. Best of all, the growth chart, which is seven feet of awesomeness, can be downloaded for free here.
