How can I implement an Iris Wipe effect?
- by Vandell
For those who doesn't know:
An iris wipe is a wipe that takes the shape of a growing or shrinking
circle. It has been frequently used in animated short subjects, such
as those in the Looney Tunes and Merrie Melodies cartoon series, to
signify the end of a story. When used in this manner, the iris wipe
may be centered around a certain focal point and may be used as a
device for a "parting shot" joke, a fourth wall-breaching wink by a
character, or other purposes.

Your answer may or may not include a coding sample, a language agnostic explanation is considered enough.
