Lcd monitors (standalone or those of notebooks) currently in use are fast enough. This was not the case with the lcd displays of laptops ten years ago. (I think this is why they're now called TFT instead of LCD.)

I've followed the link you gave and I've seen the illusion. It's very wierd how the pink dots disappear and sometimes reappear when you stare on the middle cross. I have a tft monitor btw.
