In this video, Japanese video blogger Jet Daisuke is toying with a Space Invaders Happy Button machine. Manufactured by Taito last year as part of the series' 30th anniversary, the free kiosk challenge players to simply tap its big red button as many times as possible in ten seconds.

It's a lot like Hudson's Shooting Watch device, except much bigger and it plays Space Invaders sound effects. Notice that Daisuke even introduces himself in the video as Jet Meijin, a nod to Hudson's 16-shot personality Takahashi Meijin.

The Happy Button also has a score keeping track of every player's taps, adding each attempt to its grand tally. Apparently, the machine rewards you with a celebratory melody if you manage to tap the button over 100 times in ten seconds, as shown here:
