I like ideas, especially the interactive kind:  The kind that had to bounce around off of a lot of different people in order to fully form:  The kind that evolve, and take on a life of their own, separate from the life (lives) of their creator(s):  The kind that run deep into run-on-sentances with lots of colons and parentheses, and you have to read again and double take...

Try this one out:
For Internet Explorer users, Click View, then Source at the top of your screen.
For Netscape users, View, Page info., Page source, html codes.
For Linux users, you figure it out.

OR
Right click on the page - view source - it's all the same.
Some ideas are difficult to communicate, some are easier....
