Using 555 timers and no Arduino... Only red/blue LEDs!

I take it the idea is to get the red/blue flashing really fast, making a gradient red-->magenta--->blue depending on the resistance of the thermistor in the 555 control circuit?
I like this a lot. Thermistors are non-linear in their response, so tuning this to different temperature ranges is going to require some thinking, but its a really excellent idea.
Is this a question? Click here to post it to the Questions page.
