Print these nifty standoffs, stick them to a boring plain wall with double stick tape or something, and wrap some yarn around them to make a super cool string art thing!

I included the Autodesk Inventor 2014 .ipt files for anyone who wants to edit them with inventor.

Materials:
Standoffs (Small, Medium, Large)
Double stick tape or equivalent
Yarn

Print as many standoffs as you want, I printed 12 of each, and make sure they are scaled according to the attached pictures.

Stick the small ones to the wall first and wrap the yarn arround them, then the medium ones, then the tall ones and you should have a pretty groovy wall piece instead of that boring plain wall.
