The Camera Dolly Wheels with GorillaPod SLR-Zoom Tripod and Mini Ballhead
from B&H Photo
is a combination of a very strong "SLR-Zoom" flexible Gorillapod with a perfectly-matched ballhead and miniSkates Tripod Dolly Wheels that turn the tripod and head into a video dolly for smooth tracking, panning, and arcing camera moves. You can have the camera glide over a small object, or move along almost at ground level. With optional adapters, this is a great dolly for smartphone cameras also.
