I created an animation of the Arecibo message in less than 1kb of Javascript: https://js1k.com/2017-magic/demo/2843 https://js1k.com/2017-magic/demo/2843 Here's a video of the animation playing: https://www.youtube.com/watch?v=zMzwmdaloXc https://www.youtube.com/watch?v=zMzwmdaloXc It was a lot of fun to put together, and I know where was a lot of human thought put into the message, but after working with the data of this message for dozens (hundreds?) of hours finessing it and making it as small as possible, the longer I looked at it the less I believe any alien receiving it would be able to decode the meaning we communicated in it. I imagine it's evidence of terrestrial intelligence for aliens who might wonder if they're alone, but I'm not sure how well the intended meaning of the message itself will come through to a non-human being if it's not even obvious to a human being that already knows what it is.
