This museum highlights the history of artificial limbs through poster images and 3-dimensional models. Some of the earliest ones were actually pretty complex, but because of the materials they were constructed from, they must have been quite heavy. Recent advances in available materials have led to both lighter weight and more natural looking prostheses. Some amputees use their prosthetics to display art.
The island on which the museum resides was used for a research project to find virtual world support for amputees learning to use their prostheses.
