Inverse Calculator: Find Complex Representations of Numbers

[CRGreathouse]

I'm looking for a particular tool I once came across. It took a decimal number as input and tried to give some calculation which would return that number as the result. I'm familiar with http://oldweb.cecm.sfu.ca/projects/ISC/ISCmain.html, but neither of these is the tool I'm looking for. These tools are essentially lookups on large tables; the one I remember was a program that found increasingly-complex representations of the number that more closely aproximated it. Plouffe's tools are online; this one was downloadable (a console application, with source code I think). The documentation, such as it was, mentioned the ISC and explained how the two were different.

Does anyone know what I'm talking about? Failing that, does anyone know of something similar?

Maple's gfun is similar, but doesn't quite fit the description.

I finally found it, so I thought I'd mention it here in case someone else wanted to use it. It's RIES, by Robert Munafo:
