Here are the steps to create a post it note 8bit Link on your wall:
1. Figure out what 8-bit creation you want on your wall.
2. Buy post-it notes, realize they cost WAY more than they should in the store.
3. Buy them anyway, its art baby!
4. Get the picture on your smartphone or print it(like its 2002 inkjet style)
5. Put up one post-it, snap a pic
6. Put up a few more
7. Snap a pic
8. Screw up a bit, start over again
9. Snap a pic
10. Realize half way you were over a few centimeters and try to backpedal
11. Snap a pic
12. Get really close and get really excited because this looks really bad ass
