From Phil Bevan:
This application allows you to overlay an analog clock onto a picture that may be selected from the pictures held on the iPhone. The clock may be customised in a number of ways.
Pressing on the clock and moving your finger allows it to be repositioned.
Pinching on the clock face will allow resizing of the clock. Tapping on the information button will display the settings allowing you to customise the following clock attributes Hour Hand Color Minute Hand Color Second Hand Color Display the Clock outline Display numerals 3,6,9,12 Outline Color Display the second hand Fill in the clock face The Opacity of the clock face (how much you can see through it) The graphic used to mark the intervals, Strokes or Dots Pressing the picture button will allow the selection of a backdrop for the clock.
Once the picture is selected you may want to readjust the clock settings to match the new backdrop. It is ideal for setting your Phone on a stand on your desk giving you a Picture customised with a Clock.
