You compare it to using a TV remote. What about if someone liked to open their TV remote, dick around with the innards, change the button layout and stuff, and prettify it?
That would be a strange hobby but I guess it would qualify.
More than giving names and assigning poster art to things on your computer so they show up on your TV.
Not saying that it’s a pointless thing to do, just saying it’s not something a rational person would call a hobby.
