How to test your processor to destruction using Satori!
Here's an innocuous looking Satori canvas. It looks innocent enough, but it contains some of the toughest zoom rendering that you can throw at your machine.
I created it to benchmark my current machine, and use it as a floating point, number-crunching comparison with the next rebuild of my workstation.

What's so nasty about it?
When you download the zip file (below) for this canvas, you'll find that it also contains three "Fibonacci" brushes. These brushes can also be found at Satori Central.
The Fibonacci brushes are composed of up to 144 small dots, each of which is a soft-edged solid brush.
I have painted a random series of strokes, and (here's the killer) replaced the original colour with new colours, but still using the fibonacci brush to do so. This means a lot of processing power is needed to render zooms at high resolution.
Let's get zooming
Now follows a series of zooms, each twice the power of the previous one. So: x2, x4, x8, x16, x32, x64, x128, x256, x512, all the way up to x1024. I stopped there because the image got rather boring, as did the waiting.
I used only the "In" button on the Zoom Palette (as well as the "Hi-Rez", obviously). The times given here are for the Hi-Rez zoom renders fron one stage to the next, I.E. from x32 to x64 for example.
Although this image was in a sense purposeless, there are some rather lovely ethereal colour effects happening especially at very large magnification, not unlike exotic microbes shimmering under a microscope.
Here's how long the series of zooms took to render on my old machine
compared with the times on my new machine.
