Lately, I've been spending more time carrying around and capturing ideas in my pocket Moleskine gridded idea book.
One idea captured in the idea book in February 2004 was that of a digital Moleskine-like pocket notebook, inspired by an email exchange with artist Witold Riedel. You can see the sketch below (click for the larger version):
The idea was to have a high resolution display and input area, combined with wireless (WiFi and Bluetooth) and wired high speed access. Witold's idea was to have the digital Moleskine generate an RSS feed of sketches, to be shared with other device owners and folks on the net. This way you could check for new sketches and then click to view them on your digital Moleskine.
Not only would it operate as a digital sketchbook, with overlays to simulate paper textures, gridlines and rules and so forth, but it would also be a viewer, showing your RSS subscriptions to other digital Moleskine devices out on the net.
It would also have USB and Firewire ports for input and output, a VGA out port for display of sketches on screens and overhead projectors, and an SD slot (or two) for storage of sketches. I imagine flash memory would be most sensible for a device like this, for both size and durability.
After sketching the idea, I thought it might be nice to make the input/view screen a two-page spread rather than a single page. Hey, I'm dreaming here, why not? :-)
It would need to be sturdy, so I imagine high resolution "digital paper" would be best for the screen/writing surface.
Anyway, it's a wild idea which will likely be realized when my son is my age, but you never know. I figure by putting the idea out there now, it might happen and maybe I'll get some royalties to put my him through college. :-)
