Trade shows and exhibitions are so last-but-one century.
People pay vast amounts to have ‘stands’ so that many more folk can pass by semi-somnolent and maybe pick up horrible free pens and product literature.
Today’s invention is to have an exhibition space filled with ‘stands’ which are free to move very slowly from place to place. These would each be mounted on an electrically-driven trolley and allow anyone to hop on and off (or wheelchairs to roll on roll off).
Just having stands appear next to each other in interesting juxtapositions would be exciting and thought provoking, but I’d also suggest having stands of differing sizes so that many people (eg startups) might have one that was like a powered shopping trolley.
How about stands which could be directed by delegates’ mobile phone messages?
