Dusk tusk. That was my attempt at a sunset.

That makes sense. Darned socks were a bit of a stretch. :)

sorry. that looked to me like a red jello cake and two hands either refusing it or shoving it, but I still would have gone with cake take, LOL

I hate when my socks get stretched.

They never fit right, afterward.

Well, on the bright side, at least you have socks for your left foot.

ll
el 7 c40 = r1-4, r14 w
ll
el 5 c28 = r1, r12-14 w
ll
no matter where the 5 in c28 goes, c29r4-5 will be white.

And that's all the moderate lookahead I can find.
For deep lookahead,
If the 5 in c28 were to go in r2-6,
> the 2|3 in r2-3 would trigger the 2 in c30 and force it down into r4
> which would trigger the 2 in r4 and force it right
> which would trigger the 5 in c31 and force it down (into r4-8)
= which runs into the pixel in r9 making the block too long.
Since we've run into a conflict, our original posit is wrong and so c28r2 must be white.

ll to finish

Found to be solvable with deep lookahead by infrapinklizzard.
