I've given in - and from now on I'll use a MySQL database to continuously store all the readings from the various ROOMS sensors dotted around the house.
The database is very simple :

For those who wonder about the first field (id) - it's there to make usage in Ruby on Rails easier for a novice like me.
And to get the data out - here is a simple code example in Ruby
At long last I managed to get my first Ruby On Rails application displaying something :
using the "acts_as_dashboard" gem I managed to pull data from some of the Jeeduino/Arduino sensors dotted around the house, and using various AJAX calls I can get the screen to dynamically update these values.
I know - this is not terribly advanced, but at least it is a start.
I just bought a 5 metre roll of RGB LED's - after reading this Jeelabs article. I even bought the necessary MOSfet transistors to build the driver board.
But then I came across this story - and I happen to have a BlinkM MaxM laying around
Using MaxM with flexible RGB tape
A single BlinkM MaxM can easily drive a 5 meter (16 ft) roll of the flexible RGB SMD LED tape that’s used for architectural lighting. Each roll contains 150 RGB LEDs.
Each LED in the tape is a SMD RGB "5050" LED, capable of putting out about 6000mcd. The spacing between LEDs is 3.3cm (~1.25"). Read more
