<p>A round ''sprite'' that can be placed on a <code>Canvas</code>, where it can react to touches and drags, interact with other sprites (<code>ImageSprite</code>s and other <code>Ball</code>s) and the edge of the Canvas, and move according to its property values.</p><p>For example, to have a <code>Ball</code> move 4 pixels toward the top of a <code>Canvas</code> every 500 milliseconds (half second), you would set the <code>Speed</code> property to 4 [pixels], the <code>Interval</code> property to 500 [milliseconds], the <code>Heading</code> property to 90 [degrees], and the <code>Enabled</code> property to <code>True</code>.</p><p>The difference between a <code>Ball</code> and an <code>ImageSprite</code> is that the latter can get its appearance from an image file, while a <code>Ball</code>''s appearance can be changed only by varying its <code>PaintColor</code> and <code>Radius</code> properties.</p>
