cool pic I would like to try too - but how?

hey there
there as a post recently on the social networks of someone who did a panorama while rolling down a hill
http://thumbpress.com …-while-taking-a-panorama/

and I was trying to figure out HOW to do it.

as far as I can guess...you pick a single point at infinity and then you start slowly going through 360 degrees
with multiple exposures (how many? how to decide?)
and then...how do you stitch it together?
(i am not familiar with too many programs and only a cursory knowledge at that...)

but I am willing to hear other ideas, PLEASE!!

Looks like a similar technique to this.

hmmmm. i will have to learn a decent amount of photoshop....but the video is really quite good.
Thanks for the heads up!!
