My pipe dream, hanging my work in the Museum of Modern Art, or any museum for that fact, has arrived, compliments of Dumpr and Museumr.
It rather inspires me to do something huge, seeing my pieces at this size.
For those who would really like to have their work hanging in a museum, there is a process. The Curatorial department of the Metropolitan Museum is a good place to start or Educational Resources. There are as many museums as there are art works, but some have more presence than others, atrracting and holding bodies of work from masters both past and present.
Artcyclopedia is a great leaping off point to explore art in virtual museums.
