If you are in London and have some time to spare then do visit Tinker.it and take a look at their office window where they have built Snowflake which is an interactive display. The original Snowflake concept was devised by Andras Szalai, Jon Hewitt and John Nussey and Tinker.it drew up with this cool idea of RFID enabled snowflake generator. Passer bys would surely be attracted to it and they could use their Oystercard to discover the magic of snowflakes before winter bids goodbye this year. Believe me you would have never before seen such snowflakes in different shapes and sizes. It will be in their office only till the month of February so find out what kind of snowflake you are before they are gone!!
