Place: crowd pixel art

In April 2017, an intriguing story unfolded on Reddit. For April Fool's Day, they conducted a small experiment: create a blank canvas for users to edit anonymously, named Place.

The rules were simple. Each user could choose a pixel from a palette of 16 colors and place it anywhere on the canvas. They could use any colors they liked, but had to wait 5 minutes before placing the next pixel.

After 72 hours, the outcome was astonishing. A collaborative piece of art that even surprised its creators. From a blank canvas and simple rules emerged this:

Evolution of /r/place

Every pixel you see was placed by hand. Each icon, each flag, each meme was meticulously created by over a million people.

I discovered Place when it was almost over. A fantastic post by sudoscript tells its complete story.

The experiment began without any announcement, and users started placing pixels randomly, just to see what they could do. Within minutes, the first drawings appeared on Place. They were quite basic:

But working alone, one could only place a pixel every 5 minutes. Creating something complex would take too much time, and someone came up with the idea of using a grid for collaborative drawing, starting with an innocent Dickbutt.

From there, the community began to coordinate for more complex creations, and drawings started to appear rapidly:

Over the next three days, various factions formed, teams with specific goals, battles for canvas dominance, coordination between different projects…

For example, a group from 4chan called The Void attempted to fill the map with black pixels.

Here's the final image. Clicking on it takes you to an atlas explaining each part of the artwork:

Web riddle games

To grasp what a riddle game is, I recommend clicking the image to visit the website before diving into this post.

El Desafío

El Desafío is a riddle game. Riddle games are a series of levels, each presenting a puzzle (often involving lateral thinking). Solving one leads to the next level by altering some text in the URL.

Riddle games like Cicada 3301 have gained significant attention. Cicada 3301 is an enigmatic organization that annually releases puzzles to identify top crypto-analysts. It's speculated to be a recruitment tool for the NSA, CIA, MI6, or hacker groups.

One of the few Spanish riddle games was featured on the now-defunct Javi Moya's blog.

Other notable riddle games on the internet include:

If you've checked the above, you'll notice they all share a similar style. Over time, this genre has developed common characteristics and levels. There are even dedicated communities for riddle games.
