Thanks Keith! I have included
movement and
speed in to the list... they both certainly give plenty of scope; especially the former as it can be anything from transport to running water to a flag flying to a whole host of other ideas; likewise the latter doesn't have to be something moving fast!
Colour also gives us some scope and if it gets any votes maybe we should ask for an actual colour to be specified; that way, if it comes out top then (hopefully) we shouldn't need a further poll to decide the colour... or if its a tie there we can opt for tartan!
As for your other (esoteric) idea, again we could ask for suggestions if that one gets any votes... or maybe we need to include some more options in to the list (like
Other - please specify!)
