Macromedia/Adobe's Flash has quickly become a standard for low bandwidth
animations and intros. Flash can be used to perform various tasks, from whole
websites to smaller banner ads. Flash's edge comes from the visual impact it can
have on a webpage while using the minimum of download time.
Although nowadays, with search engine rankings such a premium commodity, it is
used mostly for small area's of the screen it can still be used to great effect.
www.kc-commercial.co.uk is a great example of how Flash can be used to add a
touch of movement and style without compromising search engine rankings or user
download times.
Another good example of flash used for small components is
www.dudeskin.com, this has a funky flash intro and also makes use of
flash for banner ads, and sub navigations.
