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...

Kingbright recently released 01005 (0.45mm x 0.25mm x 0.2mm) sized LEDs, which afaik are one of the smallest ones easily available. One neat idea would be to pack those on DIP14 sized pcb, making tiny neat character display. I guess something like 5x7 or 6x8 matrix could be doable with small mcu to drive them.

For those 1mm addressable RGB LEDs I've been thinking how you could do cool cyberpunk looks by stringing them on some hairthin magnet wire and sticking them on your body/face/hair/etc. Blend them in with some latex or something if needed. Just need to hide the controller/battery somewhere.
