Some free rigs for (X)SI still floating around on the internet...
In no particular order (& I am not sure if they all still work)

Feel free to add to this list (as it is far from complete, I'm afraid)

Matheus Matkovic's rig: http://www.matkovic.com/anto/xsi_rigs.html (damn nice, by the way)

thank you

thanks, but this one was made for unusual purpose, like transferring motion capture with XSI Foundation (no MOTOR), game walk cycles... there are tons of controls for walking, but nothing like stretchy bones and so on... JAVA code is horrible, I made it on the fly through the few years, just by adding what I needed form time to time. It's for XSI 6, I'll be surprised if it works with newer Softimages.

Over at XSIBase "everyFrame" presents a Softimage version of the Maya rig BeeBoy:

Javier Vega has just released "Flacobot V1.05", which is actually a second version of his original "Flaco" rig.

Hi to everybody,

Another free rig can be added here.

I finished this rig for practice in animation's lessons, and I want to share with all the community.

Enjoy with the rig!

muchas gracias Zao nice going with the color switching feat. it's cool for multi-character interaction (would be fun if you could animate that).
i like the synoptic and new model too.
keep up

@zoa3d - My post, right above yours, also announced the Flacobot...
