Earth 1.02 - Display of a rotating Earth for the Newton MessagePad. Earth is an application that displays a rotating Earth. An info area is at the left upper corner. A close area is at the right lower corner. On the lower edge of the application is an invisible speed bar. Tapping the left side of the bar will speed up the rotation of the earth. Tapping the right side will slow down the rotation. You may drag the application anywhere on the screen. The earth will appear in grayscale on models running Newton OS 2.1 (currently the MessagePad 2000 and the eMate 300), and in black and white on older models. I wrote this application as a cool demonstration of graphics on the Newton. I also hoped that it would be a way of keeping people aware that we are living on a small grayscale marble. However, running this application does use more energy to run than if the Newton were idling.
