Whats It Wednesday. Reaching back in time for this one. #WhatsItWednesday

@cliffordbeshers I’m blank.

@odd It's a tough one. But I would have thought you had a better chance than most.

@cliffordbeshers An old shoe tread?

@cliffordbeshers Ice? Looks kinda crystalline.

@cliffordbeshers I’m partly thinking cigarette ash closeup, and microphone wind cover, but hmm… I do smoke now and then, and I have a microphone.

@dejus Crystalline ice is half correct.

@odd I never smoke, so I've never looked at the ash close up. By getting warmer you are getting colder. Whereas, since you are generally colder, I thought you would be warmer.

@pimoore It does have that look, doesn't it? But no.

@cliffordbeshers Ok. New ideas: ink ribbon or soldering iron tip cleaner?

@cliffordbeshers Not sure how to make it more correct… looks like looking at it from underneath, perhaps through a window. And the blue might be the sky?

@dejus I’m wondering if it could be ice on a tinted window (of a car). @cliffordbeshers

@odd ice, yes, window, yes, not tinted. But something else.

@cliffordbeshers Smashed in?

@odd …or a train window? @cliffordbeshers

@odd The glass is intact. It's the ice that has changed, creating this unique look.

@dejus The blue is late evening light, yes. Note that there are icy, crisp parts, but there are also smooth parts.

@cliffordbeshers Is it due to a rolled down window, or exposed to heat? @dejus

@cliffordbeshers Frozen sunroof?

@odd The latter.

It's a frost layer on a window pane, photographed at the end of the day, hence the blue light, with a street lamp providing the highlights. The structure is half melted from the afternoon's heat, which caused those smooth ramps. Also, this is really small, perhaps 2cm wide, taken with a 1:1 macro lens, so the depth of field is razor thin. This means that as you adjust the focus, you see different cross-sections, each with a different shape.

So, yeah, my first #WhatsItWednesday was pretty easy, so I tried the other end of the spectrum today.

@pimoore@dejus @Odd got close enough that I spilled the beans.
