You've GOT to check out Heater Sitarzewski's work.  Because she's an artist.  A real, honest to God artist.  And her medium is . . . her son's lunch box!

Every day, Heather sends her son off to school with a lunch that doubles as brilliant art.  It's hard to describe but she uses food coloring, different colored produce, and food shapes to turn her son's lunch into cartoon characters.

Some of the examples include Snoopy and Woodstock, "Angry Birds", Miss Piggy, SpongeBob, and Goofy.  You can see all of her lunches on her blog, LunchboxAwesome.tumblr.com.
