Sort of a conceptual yellow sticky note sort of thing. Drag the little though squibs around, maybe next to the topic circles (which you can double click to change). Click on a squib to open it. Type your text, or choose its color and smiley face. Click on the x to close. Import your own pictures and stuff for the background and save it or share it with others. Use the recycle bin to recycle your thoughts. Or type a bad memory into a squib, then gleefully watch it get recycled.
