And the best part is, it seems to continue with all numbers containing an even amount of 1s before the decimal. For instance:

111111.1111111...
11111111.1111111...
1111111111.1111111...

Something I like about numbers, sometimes they're blatantly beautiful, all of the other times the beauty is cleverly hidden...

I saw this recently in somebody's tagline:

111,111,111 * 111,111,111 == 12,345,678,987,654,321

1111:

The concatenation of the prime number 11 with itself.

1111 equals 112 + 122 + 132 + 142 + 152 + 162. [De Geest]

1111 = 11 x 101 in base 10 and in base 2, where 11 and 101 are both prime in base 10 and base 2. [Shafer]

The sum of the digits of the first 100 primes. [Wilson]
