@baarda Seems like a fall risk for the elderly
@JonCorbin @baarda my wife has MS and can get dizzy spells. I wonder how good this carpet would be for people with similar issues...

@atzanteol @baarda Yeah, I love playing with perception to encourage safer behavior (see playing with lines on roads to encourage slowing down), but you always should consider how your creative solution might negatively affect some folks.

Generally you don't want to do things that will make it difficult for people to keep their balance.
