comment Manipulate - Flickering graphics
@belisarius I was wondering about that myself. Does it really matter? No value of t gets out of the Manipulate to the Module, thus updating t does not cause interference with the symbolic nature of t in the equations. Generally of course I agree with you, but does it really have any risk here (apart from giving t any value in the Module)?

comment Manipulate - Flickering graphics
In your example, time is undefined. Nevertheless, when I set it to any numerical value, the example works as expected. If you refer to the fact that the red dot moves so fast around {0,0} that it seems to cut through some distance, you could try holding down the Alt key while moving the slider which slows down updating. For me it shows a smooth movement around the focus.

comment Negative power instead of fraction
Why was this downvoted and even flagged for closing as being "too localized"? I think it is a perfectly reasonable question given the aim of the poster (using external software) and is not trivial to solve based on the Documentation.
