Following links from  the Baloon3d page on squeak.org:

http://map.squeak.org/package/178bd01c-f698-41ab-9c73-d9278c65c241/default

there are/were versions for (1-1.0.3, 2-1.0.4) 
--however both links end on  pages with broken links to sars

Baloon3d home also has a dead link to a 'Balloon3D' removal  package.

Qs: is there a copy of the original Baloon3D packages out there somewhere that

might be used to build a new package, or is it necessary/desirable to start again?

- any papers or design info that capture key decisions?

I'm aware that 3D on Squeak was in a way supeceded by Croquet/Cobalt

However that has a rather different use-case.

- I'm not too bothered by h/w acceleration.

- an elegant/customisable renderer is of more interest so happy to have more of 

it in Smalltalk provided speed is tolerable

thanks,

David Duke
