Thank you! This is very helpful. I will look into nsview and looping over the pages.

Similar to this post: animate-in-drawbot-without-exporting-gif.

Would it be possible for DrawBot to re-run the script at a specified rate, similar to how Processing uses frameRate() to determine a target for how many times the sketch should refresh per second.

Calling frameRate(4) could have DrawBot update at a rate of 4 times per second, and the global variable frame could be a counter that increments each update, so something like oval( sin(frame) * 100, 100, 100, 100) would draw an animated oval.

This would be very useful for previewing an animation within DrawBot, without having to export to a gif or mov file.
