Yes, this effect shows up when you view http://www.testufo.com/#test=eyetracking on a CRT, then again on a common LCD.

If you're running "ToastyX Strobelight" (easy lightboost programming utility) on a 120Hz LightBoost-compatible monitor -- hit Control+Alt+Plus to enable LightBoost strobing, then Control+Alt+Minus to disable LightBoost strobing. Control+Alt+1 will program the strobing to 1.4 milliseconds, while Control+Alt+0 will program the strobing to 2.4 milliseconds (oscilloscope measurements). The 1.4ms-vs-2.4ms is actually noticeable in the castle at the top of http://www.testufo.com/#test=photo&pps=1440

It's a very interesting exercise in hacking LightBoost 2D as a programmable-persistence computer monitor (100% software hack; no hardware modifications needed; no 3D kit needed)
