Cool. Unfortunately though, on my regular setup of Firefox on Windows, the background image abruptly 'runs out' shortly after the "You're currently travelling at 70000 pixels/second" message appears, leaving me with a blank white screen. I believe this is due to this browser bug I've just found out about: https://bugzilla.mozilla.org/show_bug.cgi?id=816917 https://bugzilla.mozilla.org/show_bug.cgi?id=816917 Fine on Chrome though.
