I really like openclipart.org for any kind of artwork, yes there is a talented design team within Canonical but I want to make community better, so I had to mention this web site.
I made a remix for a subsystem like Unity7 remix Ubuntu Web Remix and others and 20.04 or any later called procyberian systems distribution(also for other operating systems or hardware platforms that has no operating system)
Here is my logo remix : https://openclipart.org/detail/329737/procyberian-systems-distribution
It seems like Ubuntu, Canonical and Trisquel and also BSD Daemon
Thanks see you!..
