Excellent ideas! However, let me stress that any submitted formations need to follow the guidelines as listed on http://www.teammandrin.com/vrw4way/2006_additions.html. A formation that cannot be described in terms of an arm, leg, or foot grip (like a totem) or has a dock on gear (like a totem) will not be considered for the dive pool, unfortunately.
This means that totems, spocks, monkeys, piggybacks and any head docks will be relegated to the artistic freefly crew for now.
And let's remember that we only need 1 advanced block and 1 advanced random, and I think we may have already gotten those. We're really looking for fun and creative intermediate block moves!
