Warning: this is just going to be a random set of instructables I saw the past few days.

An easy to make IQ paper toy cube

DIY Magnetic stirrer with hot plate for less than US$30 

A different kind of made of paper toy cube

DIY sterling engine 

And another paper toy 

Origami Ball 

And Oooh look! your very own wooden gear clock 

Now your job is to decide what kinda of theme (if any) I had for this bumper set. =)
