Torpor Download Page

You can download copies of our Windows software. These programs run on Windows 7, 8, 10, and 11.

Note that Fred's Fractal Factory and Viewer works much better if your video card includes a GPU. The Factory calculates fractals 10 to 100 times faster with GPU support. And the Viewer supports automatic almost always on antialiasing if a GPU is active.

The Silicon Mirror and Spectrum Shift do not require a GPU.

We have recently ported Moe's Image Viewer and the Silicon Mirror to the Mac! This can be purchased from the Mac App Store for $5.99 .


All our windows software is currently free and does not time out.

You can install copies of our Windows software via the Microsoft Store app:

Installing via the Microsoft store is safe but somewhat clunky. In particular, the installation may pause waiting for confirmation from the User Account Control dialog asking you if it is ok to install software from Elliot Leonard. You should say 'Yes' to this.

Unfortunately, the User Account Control dialog is often hidden behind the Microsoft Store App so the installation stalls.

You can fix this by clicking on the User Account Control icon in the taskbar.

When you click on one of the install links above, that will send you to a Microsoft website that offers you the choices of 'Download' or 'View in Microsoft Store'. In theory both options work, but I recommend that you pick the 'View in Microsoft Store' option because that seems to work more smoothly.

Clicking on 'View in Microsoft Store' launches the Microsoft Store App, which is not a web browser. In the store, click on the Install button, and then say 'Yes' about installing software from Elliot Leonard. Then you can click the Open button in the store to launch the app. If the Open button in the Store is flaky(or missing), you may have to locate the desktop icon for the program and open that.

The Spectrum Shift Paint Suite is actually a collection of 4 programs, the Palette Selector, Spectrum Gradient, Photo Alias and Spectrum Shift Paint. Ideally, when you click the Open button in the Micrsoft Store after installing, that would launch the Spectrum Shift Paint application. But alas, that is not always the case.

The Spectrum Shift Paint Suite installs 4 desktop icons:  

You should open the orange Spectrum Shift Paint icon when first starting out.


Some of our programs install more than one icon on your Windows desktop.

The Silicon Mirror and Kaleidoscope only installs the following icon for Moe's Image Viewer:   .

Moe's Image Viewer on the Mac looks like: .

Spectrum Shift Paint installs 4 desktop icons:  

The Palette Selector and Spectrum Gradient allow you to create and manage custom palettes. Photo Alias allows you to convert almost any photo to gray scale and then apply false color mapping to the image. These images can be animated and used as fill textures in Spectrum Shift Paint.

Fred's Fractal Factory and Viewer installs the following desktop icons:  


So what is with the blue arrows in the upper right corner of our desktop shortcut icons? This only occurs in Windows 10, and apparently it is a Microsoft bug. This seems to occur because the shortcuts are stored in a compressed folder in Windows 10. However, logically these shortcuts refer to our programs, which are not compressed at all, so the blue compression arrows are really a bug. The bug is completely harmless, but it is annoying and potentially confusing. We use the Wix Toolset to build our installers and I queried the Wix folks about this. They said this behaviour was Microsoft's doing, and not something that the Wix folks could fix. It is a 'feature'.
