You gotta love this awesome highly detailed hand-drawn map of London.

I noticed, for instance, the Boxpark pop-up mall that Dan showcased on this blog last year.

Bicycle Dinners
Here at the Pop-Up City, we value food beyond its role as basic sustenance. Food is a vital element of cultures and social interactions.

And, no, it does not involve eating dinner while riding a bicycle.

Chicago’s Streets Become A Life-Size Monopoly Board
Millions of children grew up playing Monopoly: I know I always looked forward to Grand Opera night where I could collect $50 from each of my opponents, and dreaded the feared Poor Tax Chance Card (fifteen whole dollars!). It embedded the names of the Boardwalk and Park Place for everyone as the best place in the city, especially if you could afford a fancy red hotel. Apparently, someone has tried to turn the streets of Chicago into a city-sized game of Monopoly. Nate Berg at The Atlantic Cities tipped us off about the new street art installations, and they’re all sorts of fabulous.

3D printing is becoming a true hype, and origami has always been restricted to the most patient and agile.

Rent-A-Goat To Mow Your Lawn
Urban farming has been all the rage, but what happens when you throw some multi-functionalism into the mix? How about goat rentals for mowing your lawn? San Francisco’s City Grazing has been keeping a herd of 50 goats to manage the growth in their pasture.

Ithaca’s Fabulous Mayor And The World’s Smallest Park
Whoever thought civic politicians were boring? Ithaca's 25-year old (!) mayor, Svante Myrick, recently decided that it was high time to lose his car. But what of his celebrity parking spot in front of city hall? He chose the obvious option: turn it into a park.

Aphrodite Of Amsterdam
Some time ago I noticed a visual artwork on the roof of the GAK Gebouw in Amsterdam's Bos en Lommer district, consisting of digital fireworks combined with flashing words that say "IK HOU VAN JE" ("I LOVE YOU"). I found out that artist Leonard van Munster is the man behind this light installation.
