This clock was created when I played around to discover a way to animate the clock hands in PowerPoint. Initially, the animations played differently in PowerPoint 2003, 2007, and 2010 mainly because how PowerPoint 2010 plays animations but with a few tweaks, it all worked well. Feel free to download and use these clocks, and I have included both a 1 minute and 5 minute timer.
Each slide uses colors and effects of the Theme on which it is based so as soon as these slides are inserted in your Theme aware presentations, they will use the look of all the other slides in your presentation. Also explore the other extra slides in the presentation that show how the animation sequence progressed.
