Belfast Wi-Fi T-shirt

I wanted to design a t-shirt to celebrate where I live. Belfast means many things to me, but as a web designer without an office, this t-shirt pretty much sums it up.

The different coloured wi-fi spots represent free wi-fi, paid wi-fi, BT Openzone, and Bitbuzz Hotspots. Points are plotted at 1" to 500ft using BelFi's current data - http://belfi.co.uk/.
