I made a cool-looking 3D gauge. Pro tip: you can use a BG layer as a second general-purpose graphics layer that's at a different depth. Just fill the layer with tiles arranged the same way they are in the BG graphics page (#5 by default), set that page as the manipulation page (GPAGE 0,5), GCLS, and draw to that page like normal.

Does the meter realy work?

It didn't at the time I posted this (it just moved with the Circle Pad), but now it does; it measures movement using the accelerometer. The key is CKENX336 if you want to download it.
