It's all about atmosphere. When attempting to create something, your surroundings affect you. That's why I am currently listening to Sufjan Stevens and Relient K's christmas albums and decorating my apartment with nerdy snowflakes. 
Doing a brief search of the interwebs, you are inundated with Star Wars snowflake templates which are incredible. A more intensive search provides some Doctor Who, Zelda, and even some Hayao Miyazaki designs, but beyond that there is dearth of nerdy designs. So I decided to create my own.
