Creating that fast blinking effect

i need help… how do you create that fast blinking effects you see in some websites?

example?

One frame has the object the next frame doesn’t and then it just loops. its probably a frame rate thing, or a setInterval thing, that’s the only way you’re going to create a fast blinking effect.

try putting one keyframe, and two blank frames. or any combination of the two…

Trial and error.

yeah, I did it like that and works great, framerate 50.

Thanks a lot guys! :}
