Snocrash | Minecraft: Daylight sensor button @sno_crash | Uploaded 10 years ago | Updated 3 hours ago
Hope you enjoy this patronizing and sarcastic video :-)
It's all in good fun people - just joking around, so don't take the tone of the video too seriously!

But on to what it is -
Xisumavoid posted a video with a daylight sensor: http://youtu.be/9mh75UHN1tA
It was rather large - so we compacted it.
What does it do? It allows you to right click on a daylight sensor which produces a pulse similar to a button.
