Here's another one very similar to Piper, although it is probably meant more for database integration than for application integration: http://www.lionbioscience.com/htm/c_1/bereich_index.php4?section=c_1_1 Check out this screenshot and note the dots in the center of the links, eerily like Pied/Piper's: http://www.lionbioscience.com/img/c_1/c111_big.gif The funny thing is, this is a bioinformatics application, and the company now employs Peter Rice, who, some may remember, was the project leader of EMBOSS and a regular correspondent on the TULIP (the orginal name for the Pied/Piper UI) mailing list. But of course he started working there before any code was written for TULIP, so the similarities are a coincidence. Cheers. Jeff
