Simple test automation, with no moving parts.

Can you see the 74? This is an Ishihara Color Test. Its used to help diagnose colour blindness, people with certain forms of colour blindness would not be able to read the text contained in the image. The full set of 38 plates would allow a doctor to accurately diagnose the colour-perception deficiencies affecting a patient. The test is ingenious in its concept, yet remarkably simple in its execution. No complicated lenses, lighting, tools or measuring devices are required. The doctor or nurse can quickly administer the test with a simple and portable pack of cards. The Ishihara test is an end to end test. Anything, from lighting in the room, to the brain of the patient can influence the result. The examiner will endeavour minimise many of the controllable factors, such as switching off the disco lights, asking the patient to remove their blue tinted sun-glasses and maybe checking they can read normal cards (e.g. your patient might be a child.). End to end tests like this are messy

Fishing for bugs.

You probably don't know, but I'm keen on fishing (Honest! Ok, maybe not, but bare with me...) I spend my free time, by the river bank or out on the sea searching for 'the big one'. The big catch that'll stand as tall as me, and feed my family for a week. My dream is to be the guy standing next to his prize-fish on that black and white picture behind the bar. Over the years, I've become reasonably skilled. I usually find a fish or two when ever I'm out on the imaginary water. I've learned where they live, where they spawn, and of course where's best to catch them. For example, There's a little bend in the river upstream from my home, that has some great fishing spots. The overhanging rocks protect small fish from the predatory eyes of birds, and people. Of course where there's small fish, there's usually the odd big fish or two. Ok, lets imagine that fishing had a profitable side too, and wasn't just a [fictitious] hobby. For exam
