[My path to Quaternions]

I came across Quaternions in Second Life and after a struggle to understand them gave up.  But, after looking at this video just once (so far) an understanding has begun to dawn.  So i thought I would offer it to others who have stumbled onto SL's Quaternions as a path to understanding them:  Youtube, Quanta.

However, I have not yet achieved Quaternion nirvana.  I'm still working on transferring the above to SL and Blender implementations.  But.... Progress!!

[Marketplace: search without demos]

Hi everyone, I hope this topic is appropriate here...  I just want to share something I discovered.

I am relatively new in this incarnation and don't have much (or any) Lindens at the moment.  I'd like to find free stuff in Marketplace but when I do so I am spammed by a ba-zillion demos.  I found that I CAN do this in marketplace by using the same syntax as in Google searches.  

For example, if i search in Marketplace for 'Gifts' and then sort them by price, lowest to highest.  I get spammed by a ba-zillion demos.  However, if I change my search to 'Gifts NOT demos' (the capital letters are important), then i get rid of the demo spam.  (Some still do sneak in but this gets rid of most )

Happy shopping!!
