Complete 20-inch ballscope video is available

[Howard Banich]

Hi everyone, 

You may recall that my laptop froze halfway through Pierre's 20-inch Ballscope presentation during the Saturday morning session on October 11. Pierre has made a corrected video so his entire presentation can be viewed along with the rest of the Saturday morning video, and it can be seen here:

We decided to keep this as a separate video so we wouldn't lose the viewing data on the original Saturday morning video. I've also posted this link in the description box of that video. All told, this year's workshop has already been viewed over 1100 times on YouTube - not bad for the videos being available for only a week!

Thank you Howard! It was a special pleasure to see Pierre presenting his awesome work on the first video! (We've been brainstorming another ballscope of his design on CN some years back).
