rejigging of past experiences.
We have experienced 'red' we have experienced 'blue'... why can't we put them together in a new way to create red and blue stripes even if we haven't seen red and blue stripes before?
We have clocks, we have radios, stick em together, you get a clock radio. BRILLIANT!
And i guess the more fundamental you take an experience down to, the more originally you can place it with other experiences, and the more novel you can create your imaginings....
