I just stumbled accross the online video archive of the Parliament of the United Kingdom, where meetings of the last 12 months can be watched. (The written records going back centuries are partially available online, as well.) In theory, this allows everyone who has a vague idea about the British Parliamentary style to experience it with their own eyes -- the only obstacle is to sift through the boring stuff where only one or two members are present and find the good debates between e.g. Gordon Brown and David Cameron.
Among the more interesting videos I found is the motion for a humble address in the Lords (at just before the 2-minute mark) and the state opening of Parliament by the queen.
