The DIY SpiderTrax Rotating Video Dolly project was introduced to show others how they can make their own DIY skater mini dolly, to get video footage similar to the P+S technik Skater Mini.

There will be a limited first run of units, so if you have any interest in the DIY SpiderTrax Video Dolly kit, check out the website and drop your name @ http://www.SpiderTraxDolly.com and complete the form.
