The diffuser really makes this. The resulting effect looks great.

It really did! It looked much better than I hoped, I really liked the result.

I was about to comment that I also made a small LED panel, but then realized it was me.

Here's the latest LED thing I'm working on (the design isn't mine): https://immich.home.stavros.io/share/oXerU8gnLn-dNHunPOg8lM8...

Jokes aside this is super cool. I always find LED panels really interesting to look at under the hood. I’m so picky about the ones I like to use almost purely based on vibes when filming. They’re just one of those things that you immediately know you’re going to love or hate in post the moment they hit your subject

What can I say, I'm addicted to LEDs. I tried so hard to not make that cube above, but I failed.

On the topic of small LED panels, Jason of Evil Genius Labs has been making some really small LED panels [0] with addressable 1mm x 1mm LEDs (yes, individually addressable AND only 1mm on each side!). Fitting 128 onto a 1" circle is pretty sweet.

I keep meaning to design some PCBs with them [1] but it's too far down my ever-growing list of projects to see the light of day...
