Hello B. Surendranath Reddy <bsreddy@HD1.VSNL.NET.IN>:
I had some problems, which may have been on either my end or
your end.
1. I couldn't get your Kepler demo to load -- I think you have
a file name messed up. I poked around your system and found
the Kepler demo page, but couldn't get the Java app to run.
2. Your first 'chase' demo made my browser die. Maybe my fault.
