Re: [DIYbio] Re: least risky human hello world?

I never found NIR camera images too interesting, but longer-wavelength
IR has always been cool ('heat vision'!). I was reading about this a
few years ago a bit more, but it would be awesome to add somewhere...
maybe the nose would be a good spot to embed a new eye? I say this
because the eyeball will probably absorb a lot of the IR signal,
snakes for instance use more of a pinhole camera than lenses
supposedly:
https://en.wikipedia.org/wiki/Infrared_sensing_in_snakes#Molecular_mechanism

(it doesn't actually sense photons, rather it is affected directly by
molecular heat vibrations)

This would not qualify in my book as a Hello World experiment though!
