I was thinking something with SailfishOS logo in the center, similar to the ones with the AsteroidOS logo. Maybe the same blue color for font which is the default for Sailfish(font color from Freedom ambience, I think) and with an all black background would be nice, IMO.

I'm getting a new computer next week! Maybe I'll try to make some sometime after I get it.

right now, I only have the LG G Watch. I'd like to get something with a round face.
