Mental Training - Enhancing One's Perception Of Time, Trying to visually follow a fast object Options

I've been interested in mental training for a variety of magickal uses. Something I've been wondering about is, is there some kind of product that has an object with adjustable speeds. To the common population, this kind of device would seem useless, but I think it could be used as a means to enhance ones ability to perceive time faster. Advantages to this could be for martial artists to be able to react to a punch faster or identifying a quickly shown clip in a movie (like in Fight Club).

I imagine it could even be possible to clearly watch a bullet exiting a gun and following its path to its target before it hits. I suspect this kind of training could lead to more potent magickal practices. Does anyone have any ideas?

Not sure if I have this in the right forum. I think there should be a forum specific to mental training.

VitalWinds. That's the answer I was looking for. Thanks. Can't believe I haven't thought of something so simple as the blades of a fan. Their stable and constantly moving when in use.

Musky Tusk. Though time control wasn't what I was looking for, that is still very interesting and I may look into that. Pretty much what I was looking for was to improve perception of time. Normal people percieve time at a very limited rate. For example, if you watch Smallville or some Superman episodes, the camera will depict the fictional characters perception of time, allowing you to see a bullet leave a gun and watch it travel in detail as he makes the rescue.
