That is impressive. I wonder how it would look like if you would show all stuff flying up there! Would it be like earth has a messy bad hair day?

Would be pretty curly indeed! Check out https://space-search.io/?search=ariane for an impression

It is quite busy up there. In some way you would expect there are regular collisions of satellites, but I don’t remember I have ever heard of any.

This is all the stuff launched by Ariane rockets, or is it related to a single space program?

Thanks for the question! These are all Ariane leftover rocket parts, related to various launches. The leftover parts are mostly booster stages to transfer a sats to GEO orbit.

Any chance I could find out about satellites flying above my home town through this? Perhaps a quick help guide could help explain how it works.

It would be cool to see what kind of sensor data is available from my garden.

Yeah should be possible to add a feature like this in the near future! Will add it to the roadmap :)
