I have a thing for insights. Sometimes simply flipping the normal order of things can make one see life in a completely new way[0] and that fascinates me no end. Eventually I started collecting these at my blog, vjk2005.tumblr.com, which has since expanded beyond a collection of insights[1][2] to include design[3][4], my ideas and thoughts[5][6][7], Photography[8][9], Japan[10][11], Travel[12], pithy quotes[13] and tidbits on technology and nature[14][15].

Apple's had a less fancier implementation for quite a while now — thumbnail scrubbing in iPhoto and FCP on the desktop. I don't have any iOS devices to see if they have touch versions of their scrubber but I do remember seeing one on an iPad demo video some time back.
reg. "And what's the motivation behind the formula for the determinant?", if I'm understanding your question right, the neat little pic at http://en.wikipedia.org/wiki/Determinant#2-by-2_matrices - might be what you were looking for.
My friend's done the same thing over at http://idiari.es. Going over the posts there reminded me how vast his range was — from architecture to tech to HR, he had insights in almost every area.
"What would it be? "
- Open source Federated P2P socnet.
"Why?"
- Software can be as closed as it wants 'cause we can always drop it for another option anytime we want since the data is still under our control, but imprisoning our digital lives into these walled gardens put up by "for-profit, maximize-shareholder-value-at-all-costs, turn-user-into-product, shove-ads-into-the-user's-stream-and-if-possible-download-a-few-into-their-throats-as-well" companies like Facebook, Twitter and Google, is a recipe for disaster as our data, our friends, our relationships, our entire digital lives, go out of our control in realtime. The situation is really, really bad and to make things worse, the people currently working on this problem are so geeky, so out of touch with the common man's mentality that their technically smart solutions will never ever go mainstream. I'm very passionate about improving the situation and I desire to make social, at minimum, a federated system like email so migration can get a little bit easier when better alternatives pop up down the line or if the user feels the service provider is starting to get a tad too "evil" for his taste.
