end sand/glass

When an anvil falls on endstone it becomes end sand. It will float but when a falling object (anvil sand gravel concrete powder) lands on it the endsand will fall down. You would smelt endsand into end glass which is a great new block because a line of en glass would act as redstone. The redstone current would be able to go up with this new block, and it would glow brighter depending on the redstone signal streanth (it would be darker as they go on because of the signal strength decreasing slowly. Different colors of the glass would not connect. I can see this being use in many redstone contraptions. The glass in endcitys would be endglass.
