I created "Ocean Walk" as an art piece. In other words, it is a world that aims to excite and move people.

Dive into the seas of Yonaguni Islands of Okinawa to explore the ruins that have been there for an unknown number of centuries. Discover the enormous pyramids and the "Stone Circle", the playground of those who live there: dolphins, turtles, and various other creatures. Click the fish and animals and they'll let you ride them.
There's also a little "game" in this world. If played well, it'll lead you to the secret "Dragon Palace". The Dragon Palace is an underwater paradise described in the Japanese legend "Urashima Taro". This Dragon Palace has been recreated in Okinawa fashion. The buildings, dancers' movements, and their costumes have been designed to realistically resemble Okinawa tradition.
Our policy when creating VRML data is to keep file sizes as small as possible while building high quality worlds. The environments of VRML viewers are not universal: direct connection, dial-up using modems, speedy workstations, slow personal computers.
To reach the largest common denominator, we need to set our target to the low end machines. Worlds with complex objects and textures can look pretty; but I purposely chose not to do so. I also aim to have people on different platforms (i.e., SGI, Windows) enjoy our worlds. For this reason, we chose not to use any functions that are only available on specific platforms.
