CELLPHABET- walk in English!

So... cell phones are here supposedly to make our communication faster and easier, right? My friend Rohit Gupta does not think so. He likes to take things slowly and make them complicated. He entered a code into his phone that sends a 0 and 1 signals to (some server? somewhere.) depending on his location.... and it displays on a big screen. Audience, in the meantime, is sitting in a pub, cheering every letter that appears. They ask questions, he answers. It took him 7 hours to write 4 words, but hey... But why don't I let him explain how it works..

You can also here a 5 minute interview with him here

And you'll even find the code here
