I did find one video, for the gear pyraminx. http://m.youtube.com/index?client=mv-verizon-us&desktop_uri=%2F%3Fclient%3Dmv-verizon-us
Overall it did a pretty good job of explaining it. Well better than i could have
As for the Vulcano cube, I could not find a solution anywhere, sorry.
Anyways, I hope this helps!
