Our very own Rachel Hobseon @ CRAFT spotted these. She writes:

This project combines two of my favorite things: crayons and rockets. It may have taken John Coker 12 years to complete this project (hey, who among us hasn’t had a case of lingering works-in-progress?) but the result was more than worth it. He’s even included a step-by-step of how he made the rockets. The detail in matching the Crayola design is pretty impressive. I just want to know if he could find a way to add in that awesome Crayola smell.
