   @recursive Do you remember when they finally solved blue LEDs and for a little while they were super trendy? E.g. Sony put them on their AV gear when they were processing digital audio because it was cool, damn it.

     Feeling impossibly old when I see cheap modern LED christmas lights and remembering that high-intensity monochrome light sources were pretty scarce when I was a little kid: probably the only ones I'd seen by age 5 were low-pressure sodium vapor lights and HeNe laser barcode scanners.

     I was maybe 10 or so when high-efficiency red LEDs became widely commercially available.
