I've been a bit stuck lately - really wanting to move on, but totally lacking in motivation. Where to get inspiration? Well, what I did was apply an old brain-storming technique - take two random nouns and link them together in some way. For my purposes, concrete nouns are best, though if only one of your random nouns is concrete, that still works. Once you have your nouns, sketch the results of your imagination.

On a side note: I found it quite hard to get these random nouns! A non-tech way is to randomly flip through a dictionary and stab at a spot, then take the closest noun. Very slow though. I did a search through the Internet for a random noun generator, discarding any you had to pay for - why feel guilty that you had to use the generator because you'd paid for it? Way to stifle creativity.
I found two I could use, both for random words, but letting you choose the category. The first one, TastyLamp is one that builds up its vocabulary by users adding words to its database. Some of the words can be a bit strange, and I don't mean obscure!
The second, Creativity Tools has its own database, and you can choose the complexity of the word you get.
I'm sure one of these would be relatively easy to write for a computer programmer, given easy access to a suitable database! (hint, hint)

The first result I had using this method, was camera/coin. The result is up above. After a few more combinations, I found I was not only sketching, but writing a lot too, and firing up more ideas and off-shoots. All good!
