Nice! Though it looks like in your version the blink is happening from top-to-bottom as opposed to collapsing in the middle. I like the blink after the toggle, but the actual blink animation in the original in preferable imo.

If you slow down the original, it does the same thing. Optical illusion I think.

Edit: only the second blink is funky. The first is how you recall.

The first (happy) blink is fractionally slower than the sad blink on purpose. I'm obsessive about details.
