Closing this now since existing tools can do it quite efficiently.
Some more examples:

text lines clocking patterns: (pass to tr -d '\n' to remove new lines)

  101010...   yes 1$'\n'0
  111111...   yes 1
  111000...   yes 1$'\n'0 | sed 'p;p'
  123456...   seq inf


binary pattern generation:

  010101...   tr '\0' 'U' < /dev/zero


cheers,
Pádraig.
