Maximalism

Although I have no formal training in the arts, I have been to a few art exhibitions and have also glanced at the cover of several books about the subject. One term I have come across is 'minimalism', and I have often wondered what the opposite would be. As google couldn't provide a definitive answer, I hand the question over to you. Is it 'maximalism'?

Here's a few members of a non-minimalistic family of pictures. As you can probably see, they are related to the nanorobots.
