Arduino driven floating black ball is the creepiest/coolest thing around

SPace Replay

Space Replay is a project by Francesco Tacchini, a Royal College of Art grad student, and Julinka Ebhardt and Will Yates-Johnson of Design Products:

A hovering object that explores and manipulates transitional public spaces with particular acoustic properties. By constantly recording and replaying these ambient sounds, the levitating sphere produces a delayed echo of human activity.


It’s equipped with a battery-powered Arduino — an Adafruit Wave Shield  in order to record and playback audio on-the-fly through  a small speaker. In the video below you can see how it moves around:

It actually reminds me of Rover, the large white inflatable balloon protagonist  of  the 60s sci-fi series the Prisoner! What do you think?

    Is this for real, I’m getting the creeps :D Totally Prisoner-material, good job!

    it would be interesting to explain how it floats and navigates!

    Well it must be helium in the ball. I liked that it recycled conversations from earlier. Specially in a closed environment like a elevator. I sure that there are things people will say in that situation that would not be said other wise. It acted like a identity absorbing all around it’s self. Socially a sponge of it’s surroundings. Great piece.

    I thought of rover first thing when I saw that

    Regarding floating+navigation i guess helium or hydrogen in the key to the former, and from the video i don’t get the idea that it’s navigating on it’s own, but a person brings it to a space and gives it a little tug to move until obstructed. Draft would guide it i guess, but eventually i bet it would end up in a corner or near a vent or something like that. Hmm maybe rotating around it’s own center would be a possibility for (random) movement, but i mechisms for that would add weight. Ideas, anyone?

    Does anybody how the shield was used for audio input? Also, where was the mike placed? This project is being discussed here too ->

    amaze-balls is all I can say

    Nothing I’ve read here or in other posts refers to any sort of proactive drive system – it’s a passive, neutral buoyancy floater that talks (pretty cool just for that). The rest is just careful video shoots in relatively confined airflows.

    Reminds me of that Phantasm movies…Scary stuff, probably the sphere form – nothing to make the eye hold on to, scares the viewer.
