Thinkature (www.thinkature.com) bills itself as 'real-time collaboration' for the Web. As a remote-collaboration tool, it's pretty darn effective, albeit with its own quirky feel.

It's easiest to think of Thinkature as a 'shared whiteboard' with one black pen, 4 shades of pastel sticky notes, and an infinite clip-art album.

Standard point-and-drag control
Pen draws freehand - black only - but the resulting lines & squiggles act like independent objects. Draw a squiggly circle, then click and drag it somewhere. You can't erase part of the line - it's an object once it's drawn.
"sticky notes" are used for text. Click - type - resize.
Connector tool links sticky notes

But deal with innovation this book does. Rather than a breathy oh-gee-ain't-innovation-neat survey, Moore takes a deep look.

Then there are those terrific exceptions that just bang you between the eyes because they're both.
