This was my fourth virtual world created for the Building Virtual Worlds class. (What is B.V.W.?)
Unlike my other virtual worlds, Sandcastle was not a game, but a story performed by two actors wearing head-mounted displays. The story was about a boy and a girl at a beach, each trying to build his and her own sandcastle, only to be thwarted again and again by a large wave.
Sandcastle was lauded for its simplicity, charm, great interactivity between the performers, and flawless networking of two head-mounted displays.
