Notice; bored

I've been going through the last of the boxes of crap at work, and found a couple of bits that were obviously accessories from a microscope which is long gone.  Thought I'd try taking a photo through one of them.

That's my noticeboard made of wine bottle 'corks'.  A quick eye-balling suggests that at the time maybe 60-70 % of these were cork bark, the rest some sort of plastic.  Now the majority (in the same price bracket!) are screw top. I still hoard the cork and pretend-cork ones for similar projects.

Pinned to it is a prescription that I've put off collecting since September.  I'm having a daily discussion with myself as to whether I am obliged to take it or not.
