So I made this totally tedious but kinda clever thing on my Nokia N70, on which as you might know – one can write Python scripts. So my script logs the cellphone tower IDs that my phone is connected to, does some rudimentary clustering analysis. This enables me to assign say a street corner the value ‘+’, another street corner ‘-‘, and two more as ‘0’ and ‘*’. Now I have a sort of triangular shape in which I walk in code. But the script knows that if I generate the sequence “++-” – it is to be translated to the letter ‘H’. So, I have the entire English alphabet mapped in trinary code, and I can write HELLO WORLD without touching my phone at any point, and send an automated SMS to a remote device.
