Not content with the functional-yet-pedestrian-looking hipster PDA (it's just a binder clip and index cards), GTD practitioner Patrick Ng applied his rather impressive design chops to building this stunning, one-of-a-kind productivity notebook he calls the mind.Depositor.

Instead of just inserting plain index cards for random note taking, I created a GTD template to print 4 tabs on these 4x6 index cards: Next Actions, Projects, Wait for, Someday/maybe. The tabs are highly useful to classify index cards into groups, just check the box and start writing to-dos. I also used plastic index cards from KOLO's Havana box to divide "Office Work" and "Personal" index cards (labeling done with Dymo's embossers). I wish I can find better quality index cards in cream color but it is difficult, so for now I'm settled with these ugly blue lined index cards.

His 4x6 in. index cards are retained with two seriously cool-looking clips he bought in Japan. Other features include a pen holder, custom dividers for "Office" and "Personal" notes, and tons of style. I wish I could get organized enough to use something like this, but I'd just continue to customize it as a form of procrastination.
