Google has been playing games with its logo and Twitter over the weekend. First came the UFO logo beaming up the second O in the Google home page (as shown below). Second came the string of numbers in Google's Twitter post.
The number string: 1.12.12 18.104.22.168 15 1.18.5 22.214.171.124.14.7 20.15 21.19 - translates when assigning letters to the numbers in a straight code you get: All your O belong to us. Perhaps a nod to Zero Wing -a computer game that was big 20 years - replacing O for zero.
Was it a test of Twitter's power to refer traffic to Google for even an oblique message? Or could it have been an oblique accounting reference - "Zero-base budgeting does not use the previous year's budget or expenses in setting a new budget, since the company's circumstances and finances may have changed".
Obviously that last one is a stretch, but if you leave cryptic messages there will always be speculation.
