Good one, thanks!

OHH Lydia!! I love the shelf...course I'm still drooling thinking of your black bed too!! Aggie...great puppy pic!! Jodi...your kitchen is sooo gorgeous...I have a case of serious kitchen envy! Nicole...what a great workout room! The dresser in our bedroom...an old dresser set from England

Oooh that's hard! My screen has value differences (which is what's being tested, not color differences) from top to bottom, and also some from left to right because it's angled. I got 28 but then had a black one and couldn't find it. I tried again with the display centered better, and still got 28 even though they were in a different order. How do you get 33? It stopped at 29 for me.
