Random beauty

I have just noticed something quite bizarre and incredible, while reading a blog entry with a compressed Archives list down one side. The entry itself is this one about anti-vaccination idiocy, on Respectful Insolence.

To simplify matters, I will attempt to recreate what I noticed here. It's simply the names of the months (with years, but they don't matter so I'll leave them out):

• January
• February
• March
• April
• May
• June
• July
• August
• September
• October
• November
• December
• January
• February
• March
• April
• May
• June
• July
• August
• September
• October
• November
• December
• January
  
• February
• March
• April
• May
• June
• July
• August
• September
• October
• November
• December
• January
• February
• March
• April
• May
• June
• July
• August
• September
• October
• November
• December

It's a wave!

Quite, I'll assume, by accident, the names of the months, in order and with one or two exceptions, vary in length by a small but steady pattern from month to month. The effect will undoubtedly be different with a fixed-width font where each letter occupies the same screen/paper real-estate, but the numbers are, starting with January:

• 7
• 8
• 5
• 5
• 4
• 4
• 6
• 9
• 7
• 8
• 8

It would be better if October was a longer name, and January longer (or February shorter), but with a bit of pattern-seeking human visual perception, we have a nice little wave pattern.

How about that?
