Chrysalis: 

Grasshopper seems nice, but the Web site is a bit messy... Good point: on the top-left corner, there is a short blurb explaining what the site is about. Something missing in a surprisingly big number of (amateur) sites!
But after a quarter hour exploring here and there (tutorial, FAQ, download page...), I cannot see if it is freeware, open source, commercial (and how much it costs).
There are lot of tutorials, which is good, but not even a link to the Rhino tool!
Given the amateurism of the situation, and the sub-1.0 version number, I suppose it is free.

Rhino itself is a professional tool, costing some 995 € (ouch! easier if you are student or teacher: 195 €). At least, we can see that easily in the home page.
That's not for me (lack of funds and lack of time), but it is a well known, reputed tool.

Chrysalis is clear too: it is open source and searching for funding, hence the presence here instead of Exhibition. Seems like a good idea, I hope you will reach your objective (sorry, I can't help...).

One thing, though: you write that Chrysalis is an open source project, but I saw no link to the sources / the project.
Did I miss it or did you forgot it? A mention of the license would be nice too.
One of the interests of open source is to be able to get work / contributions from other people. If you don't advertise it, you won't get them.

Hi phi.lho, Thanks for responding! 

Well, as I wrote, it is OK here, as it is a call for an opportunity to help you...
