I'm looking for a good block to cover up my daylight sensor that would look nice with my build design. I had read the Wiki page on it and tested a few blocks that I thought would have worked, some did (glass and carpets), and some didn't (slabs, stairs, and pistons). Also, how was SethBling able to do this (you'll see it at around 1:00), the Daylight Sensor has a solid block (red wool) above it:
Could someone please come up with a list of blocks that daylight sensors can be placed under, and still detect sunlight? Please note if they decrease the light level as well.
