It doesn’t do a great deal other than generate circle arcs or segments, but does demonstrate how to:

• Draw an arc on a canvas – uses the for each number rather than a timer, seems to work much faster – see “DrawSegment” procedure, 2nd if/then (this was before the new arc block arrived!)

• Draw a segment on a canvas

• Rotate a segment on a canvas – 0 degrees may not be where you want it

• Change colour of segments

• Save canvas to image

• Use of spinner hack to always use top selection on display
