While the rainbow road was just for a day, the group behind it has big plans for future events.
150,000 London commuters got an unexpected dose of joy on their way to work June 22, 2015.
On a dreary, gloomy, and somewhat rainy Monday morning, a movement called Spark Your City teamed up with BBC1 presenter Gemma Cairney to brighten the cityscape.
The collaboration was called "Love Mondays" and involved turning London Bridge into a 300-meter (a little less than 1,000 feet for us metric-system holdouts) rainbow brick road.
When someone says "rainbow road," my mind immediately is drawn to Mario Kart. Somehow, this is even better.
Of course, Cairney was there for the special one-day-only event, wearing an outfit as loud as the bridge's bricks.
But, by far, the best part of the event was seeing commuters crack an unexpected smile.
There are SO many pictures on the #SparkYourCity hashtag of people enjoying the art (and dare I say, loving Mondays?). Be sure to pop over there for more.
But what about us who don't live in London (or who missed out on the event)? We're in luck.
According to their Facebook page, Spark Your City isn't done — not even close to it. The movement's goal is to put together a "fun and exciting journey linking 50 cities by a global chain of 1,000 events."
So maybe, just maybe, a Spark Your City event will be coming your way sometime in the near future. The best way to stay in the loop is to keep up with them on their Facebook and Twitter accounts and check out their website — because this is just flat-out really cool.
The world could always use more spontaneous joy. Don't you agree, Gemma?
