The purpose of this project was to create a personalized set of alphabet blocks for my 1 year old niece. I wanted the traditional capital, lower case, and number sides, but also superhero/cartoon characters for each letter as well as a puzzle she will be able to do when she's a little older. In order to store them perfectly in a cube I ended up with 27 blocks and doubled up the A.
My rough inspiration came from "Young Mad Scientist's First Alphabet Blocks" by Xylocopa http://www.xylocopa.com/product/mad-science-alphabet-blocks
. As a science teacher I still plan on making a more science based set one day, but my graphic design skills need work.
