I don't personally remember anything about that project, so all I have to go on is this entry in one of the site's news articles:
Anacalius has named his project to give Crono dialogue and Trigger a little more depth: "Chrono Trigger Re-Amped".
3D remake of CT
No, no, Rebirth wasn't one of the remakes. It was a CT hack by Shinrin. I think it started out very early on as mainly "make Crono talk". Later, as it evolved, among other things it had interludes in 1999 A.D., starring a different cast of characters (who due to technical limitations look identical to the regular cast) with slightly different stats. I recall seeing a preview screenshot where one of the future characters, who originally looked like human Glenn, discovers he's now a frog-person.
