His other projects are so interesting. I love this one https://rootkid.me/works/exhibit-a

The narration is very nice. Any idea of what the data could be? He mentions that it's legal for him to store but illegal to sell abroad and ranges from "bad to very bad".

It's in teh description: "launching a fully functional darknet marketplace (http://spectretjag3wni6fzt445qwgokqlxnfz7fxkicj5efxjywlinibm...) that offers a trove of illegal data for sale across borders"

Why do you need another source of irritation in your room?

I don't think anyone is arguing that you NEED this. But it's the intersection of technology and art, and says something about the way we live. You can view it as nothing more than an irritation, but I think that's a shame.

A much simpler and less cool project would be to convert a slice of the RF spectrum into an RGB value with lowest frequencies mapped to red, highest to blue, and the resulting color being how we would perceive the mix.

That would still be cool - but what I really like about this is that it says something quite interesting about human existence, how we live, and in particular how we live in cities when we are in proximity to each other.

All those inductors... Isn't there a cheaper way to drive those lights, e.g. using DC voltage+pwm?

Yes each LED channel has an inductor. I needed this because I wanted the LED to be constant current driven, to reduce flicker and improve their longevity

(and they cost like 5ct each)
