[Leica] Pi Day

[Howard Ritter]

Actually, Pi Day is observed every year on 3/14, with special attention to 3:00 p.m. (15 hrs). What was special this year is that in the 15th year of each century, we get the first 10 digits of pi on 3/14/15 at 9:26:53 in the morning and again at the same time in the evening.

So, they decided to celebrate Pi Day, something that appears once a century. Alas, in Europe, where it would be written 14/3/15, you guys are out of luck. If April had 31 days, you too could have a Pi Day, but alas, that is not to be. Because the next three digits of Pi are 926, they also decided to delay the usual 9 AM opening to 9:26 on that day.

They are made in the UK. The first model cost under $20; the second (presumably more memory and faster processor) under $100. The user supplies a keyboard and monitor.

I managed to get a couple of nice shots with my unobtrusive Lumix LX5. The first is two young girls working on some problem:
