Not a BuddhaBoard, but I thought you might like them anyway.
Karesansui, or the “dry-landscape” style Japanese gardens have been in existence for centuries, but it wasn’t until the late sixth century with the advent of Zen Buddhism did “dry style” gardens began to evolve. The earlier gardens were created where one could enter and walk around and much larger in scale. Around the eleventh century, zen priests adopted the “dry landscape” style and began building gardens to serve a different purpose. They were to be used as an aid to create a deeper understanding of the zen concepts. Not only was the viewing intended to aid in meditation but the entire creation of the garden was also intended to trigger contemplation. By the late 1200’s, the basic principles had been established and up to the present day, they have been refined and extended.
You can use your pen as a rake or to move stones in your garden. This software works in color with palm IIIc device or in black & white with palm III.
The Zen Garden application is a simulation of a desktop zen garden. The user can drag sand around stones with a rake. It has been written in Java but will be ported the application to Qt for use in PDA devices. Already works on Zaurus.
