Super Fast Mario
Kottke on the new speed record for Super Mario Bros:
NES player darbian just broke his own record for the fastest time through Super Mario Bros. He completed the entire game in just 4 minutes 57.260 seconds. But the most entertaining part of the video is watching his heart rate slowly creep up from 80 bpm at the beginning to ~140 bpm in World 8-2 and spiking to 171 bpm when he beats the record.
This is a game I grew up with and played over 30 years ago and kids are still playing it AND breaking records.
