Acceleration meter is a Flash animation that can be used to measure acceleration of a vehicle in which the phone is. It is neccesarry to hold the phone horizontally for the best accuracy (which is ±0.16m/s²) - yet another great software from LCARSD.
LCARDS has a selection of logos for rotation. Just go to his website.
Ball that slides across the screen affected by gravity.
One of my personal favourites. A simple arrow to show the direction of gravity.
Cool software by LCARSD - This is an animation that simulates Artificial Horizon as seen in airplanes using the phone’s accelerometer.
