Honestly, I needed something to relax, to escape from today. Vsauce DONGs always do the job very well: they provide a list of things to do online and it is proven to be fun. From the entire list that can be found in the video description here I liked most : We Choose The Moon, Techno.org, Furia Music and StereoMood.
We Choose The Moon is a website where you can see the whole trip to the Moon with videos, photos and a ton of dialogue and details. From the music websites I likes Techno.org the most, as it has a description of electronic music genres. Some music culture does not hurt.
