Snow Bargraph (Measuring redstone strength) - Redstone with ChartreuseK

Today I decided to mess around with command blocks some more because they're fun to use, and I'm a programmer at heart. This time I decided I wanted to use snow, the thin type not the block, to display the strength of a redstone signal. To do this I used 16 command blocks in testfor mode to check the data-value of a piece of redstone dust which is my input. They're hooked up to a clock to provide updates. When one is trigger it will use the data value of the snow to chose it's height, if it's over signal strength 8 it will place a full block of snow at the bottom and continue on the top. If it's less than 8 it will clear the top block and just place on the bottom.

I feel it could be useful in custom maps to show the progress to some kind of an objective in a smaller area that normal bar graphs which take up 16 blocks for 16 levels as opposed to 2 blocks. Or perhaps for an analogue redstone computer to show values.
