I've created a JyotsihTools channel on YouTube for better demos.  The first demo is for Tropical Skies Astrology and you can view it below.  Putting these demos on YouTube allows for better quality video demos and they will apparently be linked on the Android Market too.  There will also be some demos for JyotishTools too.  Note that the chart entry for JyotishTools is the same as for Tropical Skies.  The demo was created by using an Android Emulator on a PC and a screen capture program.

(Update: I've also added a brief demo of JyotishTools too):

Next up will be a video on how to use the settings for each program and possibly ones that you can play on your Android phone which will fill the screen providing a simulation of the apps.
