I remember this day which was fairly close to when I was hired at Mozilla. What this looked like from the Mozilla side several bugs filed [1]. Support forums had hundreds of questions about this [2][3]. The data from input.mozilla.org is gone or archived offline, I recall that blowing up as well. I vaguely recall this doodle causing a graphics crash on a specific set of hardware as well (though maybe that was a different doodle).
