I put a larger diameter face plate on my large clock/lamp to better hide the LEDS, and I think it looks much better. The face is thin and ~13.5" in diameter. The 1m 60 APA102 LED strip is mounted around a ~12.5" diameter disc. The Spark Core is inside a hollowed-out section on the back.
I really like Mark’s Juggle pattern on it. I’ll be sharing more soon. Just tell me if you’re getting tired of my posts, and I’ll cut back.

Almost perfect… you really gotta hide that wire !
Yeah, thought about using a battery pack, there’s lots of space inside on the back. I’m not going to drill holes in the wall. 
@Jason_Coon But it’s so easy !! 
Also noticed the face plate seems to have rough edges. If this is just a prototype, I agree about no hole in the wall.
Yeah, still a cardboard prototype. Should be creating wood bodies soon.
Hmmm… I’m putting up drywall in my office soon… I think I may just have to put in a clock height outlet
Looks cool. Can you please share the code - I’d love to run it on my infinity mirror clock.
This gives me a great idea for some sort of battery wall clock for my daughters room. I love it. Thanks.
