Here's another 20x36 puzzle, in case you haven't had enough big puzzles already. (And if that's not enough, Nikoli's Puzzle the Giants volume 21 has four Yajilin puzzles that are 31x45 in size! Puzzle 4 in particular demonstrates the amazing artistic possibilities that I hope to be able to achieve with more practice -- it has some of its givens arranged to form the letters Y, J, L, and N, and a giant arrow, as well as other interesting patterns.)
