Some of the embeded animation here may still be useful. I'm not sure how this will work on tablets when switching from landscape to portrait and vice versa. May need multiple versions of the animations. The aspect ratios of the different devices varies from about 1.2 to 1.7 and the tablets each have both portrait and landscape views. What looks good on one device will look bad on another. May need some new research here. See: Richard Taylor
The following show what is detected and reported on the device being used to view this..
| Number of pixels wide (screen width in pixels) | |
| Number of pixels high (screen height in pixels) | |
| Pixels are made up of even smaller components, the "color dots" on the monitor screen. This is the ratio of color dots in the height and width of each pixel - Flash 8 ALWAYS returns 1. | |
| Here a dot means a pixel. This is different than in printing. BUT, this Flash 8 version ALWAYS reads 72. |
With a bit of coding you can get what the Operating System says is the actual aspect ratio:
| Display resolution (pixels) | Aspect ratio | Decimal |

I'm seeing different numbers from different sources and not all of these links are helpful for a quick, in store, hands on experience. Fragmented, challenging, and more study needed.
