Looking for some creative ideas: We are trying to rig up an effect where a large-ish and moderately heavy trunk lid opens and shuts itself several times (and this happens pretty rapidly -- not a very laborious and slow opening/closing). For complicated reasons, nobody can be hidden anywhere near it (or in it), and we need to move it around to various positions while the effect is used (so it can't be physically attached to something rigid). I tried a system with aircraft cable through flexible metal tubing (sort of like a larger version of a bicycle brake cable) but there's way too much friction to make it practical. I would be interested in pretty much any ideas (be they electronic, pneumatic, mechanical) so long as they are safe and not overly pricy (I realize this may not be possible). Any hints about where to source the required items would be helpful, too.
And, before you ask, yes, we are keeping people out of harm's way.
Thanks!
