Awesome multi-monitor screen saver for animated GIF images – gPhotoShow

A picture is worth a thousand words.

Unfortunately in this still image you can’t tell that these animated GIFs are all simultaneously rotating, it is a beautiful mathematical sight to behold!

It was more difficult than I expected to find a screen saver which would display ANIMATED GIF images on multiple monitors (in my Windows 8.1).

After far too long searching via Google, I found this wonderful gPhotoShow program: http://www.gphotoshow.com which has a 30-day trial version I am running now both at home and work. I am writing this blog so hopefully others can find this program more quickly if they need a multi-monitor screen saver which supports animated GIF images.

I am indebted to my new friends Antonio Sanchez Chinchon and Andrew Wyer for their blogs about Harmonographs in both 2D and 3D, and in rotation, and for the “R” program source code which creates these beautiful mathematical curves.

Across several days I had generated more than 500 of these images at 1300×1300 pixels, and a screen saver is a great way to view the curves.

You can see the first 80 on my web page by clicking here, which shows both the thumbnail but if you click will show you the full-size curve in rotation. You can also click on any of the 7 images below!

The full 1300×1300 animated GIF images average 35 MBytes, so please allow time for the full image to be downloaded and displayed. Generally, the curves display with a slow rotation while being downloaded, then once fully downloaded, rotate at normal fast speed.

Before I end this blog, if your GIF’s are displaying static, rather than animated, please check this setting!

And here is another piece of the puzzle, if you use Windows-L to lock your computer (for example when you step away from your work PC) and want the screen saver to start IMMEDIATELY (rather than wait for the timeout interval), take a look at MonitorES (from code.google.com). My settings for MonitorES shown below.
