These blocks are pretty easy to use, place one on the side of a normal block and it will instantly fade to recreate the block you placed it next to. You can then place another Chameleon block on the first one and it will also fade! When you break the normal "master block" the two Chameleon blocks will switch to their own color again.
I'm not that creative, but let's see what you guys can do with it!
Really awesome mod. This would be awesome if you combine it with growing plants like melons, trees, sugar cane etc. since you could use it as in indicator on top of let's say your farm house so that you can see if your plants have grown from really far away. Or you could make an alarm system by placing a redstone ore block and when someone steps on it, all the blocks will start glowing. Or maybe an indicator for a furnace so that you can see whether your furnace has finished smelting from far away. This mod has so many uses!
