Found to be logically solvable by Gator.

did you need edge logic? i thought i solved without

What is it?
#10: Kristen Vognild (kristen) on May 12, 2011
aww :) (Brian, it's *clearly* the toe of a shoe, as the figure admires the spring posies.)

I see. (meaning...I don't see)

Ant - you definitely need advanced logic to finish this. You can use edge logic on the 2 in r5 or c5, or the 3 in r2 or c2. You could even use 2-way logic on the 2 in r5 to show that r4c1 is white, or similarly, 2-way on the 2 in c5 to show that r1c4 is white. Yet another is 2-way on the 2 in r4 to show that r5c1 is white, or equally, 2-way on the 2 in c4 to show that r1c5 is white.

However, straight line logic will not suffice.

Brian - It is an attempt to make a 5x5 that forces edge logic. (Altho 2-way will get the job done.) Secondarily, it could be that the "star" in the upper left is the sun, and the block in the lower right is a house.

Not unlike the morning alignment of planets. If you get up before dawn and look east in the next few days, you will see Venus, Jupiter, Mercury and Mars all in tight grouping just ahead of the rising sun.

or it could be a red cross decal about to be stuck on the first aid kit in the lower RIGHT corner. (as opposed to my other left)
