Well that cool idea I had been watching clips of all those years ago rolled out in Paris very recently..! This time, it even came with a unit to change the sound from piano to marimba to vibraphone to synthesiser to electric piano!
For something to take the kids/adults/family/partner/anyone really to this weekend in Paris, drop by Hall 1 at Gare Montparnasse and check out this video from SNCF.
It ends on a Sunday March 2nd (coincidentally a Free Museum Sunday) on the last day of the school holidays so get in quick this weekend before it's gone. I can guarantee you that it was a lot of fun..! :)
