I don't understand this part of the article:
"The Block Donut Rule is going around to the right side of the blocks and moving block 2 L, rather than R."
Why would one even want to move the block to the right? It's against a wall then and can't be moved anymore, and, moving it to the right brings it further away from the target.
Also, does "block 2 L" mean, move the second block one square to the left, or, move a block two squares to the left?
I'd love to see a step by step picture of both the donut solution and the "less optimal solution that one would rather think it is".

Oh and also, are the ice corners and the popup wall essential to the solution, or are they just there to make the picture more complex and confuse the reader?
