The obveRsive project has been abandoned since mid 2003, the developers have moved on to new projects.
If you are looking for other R-GUI frontends, have a look at http://www.sciviews.org/_rgui/. Also, some of the former obveRsive developers are working on or contributing to similar projects: RKWard, and R Commander.
If you would like to continue developing obveRsive - the sources are still there for you to use at the project page. Send us a mail to obversive-devel@lists.sourceforge.net, and we'll be happy to hand over control.
Here is a static mirror of the old website of Obversive. Many links, esp. for adding content, etc. are not working, and we did not bother to clean everything up, but all the information is still there for you to use.
Greetings from the obverse of this page
Your former obveRsive team
