Am I the first person to go "Woah! That's cool!" then look at the code and instantly go "WTF?!"? - Browser sniffing using `document.all` to test for IE - Browser sniffing at all! - Aborting `trace` rather than just removing it - In `init`, repeatedly calling `document.getElementById` with the same `id` instead of storing them in variables - Calling `document.getElementById` every time `parallax`, the `mousemove` event handler, is triggered rather than `init` storing them *once* in variables that `parallax` has access to
