/* 
  WARMER COOLER GAME
  
  Use a ping sensor to determine distance and then depending on the distance,
  show warmer or cooler colours.

  Built using a ping))) Sensor and connected to a RGB display.

  Uses the ping))) example in the base Arduino install, written by David Mellis & Tom Igoe

#   Twitter stream analyser and network activator (TSANA)
#
#   This script analyses a twitter stream for keywords using the twitter
#   streaming api - off the back of it, it then hits a user defined url
#   In my case this is being used to tell an Arduino to pulse a light but
#   could be used for anything arbitrary.

#   Twitter stream analyser and serial activator (TSASA)
#
#   This script analyses a twitter stream for keywords using the twitter

#   the message across to the serial device
#
#   This was done fopr LCA2012 as an extension to the more code generator that

#   This python converts an rgb value expressed in 8 bit values (eg 255, 128, 0) and returns a hex value that
#   has been converted to 565 format. This was highly useful when I was playing with some Arduino
#   stuff requiring 16 bit LCD designs and couldn't remember the hex layout.

Twitter Web Client Inline Image Removal

If you're a heavy user of the Twitter web client like me then you'll find the new inline preview feature extremely intrusive as it breaks up the timeline too much. If I wanted to use facebook or linkedin then I'd be using facebook or linkedin. Having said that, cards in Twitter are great and the ability to preview media before jumping off site is really cool - but it should be my choice, not have everything foisted on my timeline.

That the mobile client allows for this with a setting is even more annoying.

So here's the fix. This only works in Chrome but I'm sure an enterprising person could do something similar for Safari and Firefox using the same CSS. Pull requests to update instructions for other browsers are of course very welcome.
