The "other" artwork for the article in QA

I did a total of 10 ATCs for the Quilting Arts article, and some (rightfully so) didn’t make the cut.  I was very partial to the zombie and the robot, so those being in the article make me very happy.  The cupcake is a reworked design I did for someone online who didn’t follow through on her trade and I got the card back.  
Sadly, green LEDs in this voltage do not light up too brightly.  That’s why I think that though the holiday tree and the UFO are awesome, they don’t work well for print.  
So, seeing all of these ideas… what design would you put lights into?
