Lifelapse!

I love this app. Turn it on, put it in your shirt pocket, forget about it. It takes one photo every 30 seconds. On later iphones it can make a video on its own; on mine (an old 3G), it can just save the photos, and I can stitch them together using ffmpeg (specifically, ffmpeg -r 5 -f image2 -i IMG_%04d.JPG -r 20 new-vid.mpg; "-r 5" makes 5 frames/sec).

I did it the other day. The sorta cool thing is, you can see a video of my day. The really cool thing is, I can figure out everything I did that day, and how long it took! Here are estimates of my day, frame by frame:
0001-0010: computing
0011-0012: bathroom
0013-0155: computing
0156-0157: bathroom
0158-0304: computing
0305-0307: walking around apartment
0308-0310: bathroom
0311-0326: walking around apartment, maybe snacking, getting ready to leave
0327-0398: went for a walk, did some juggling, met another juggler
0399-0410: computing
0411-0420: bathroom
0421-0455: computing
0456-0457: walking around apartment
0458-0459: brushing teeth
0460-0522: nap
0523-0531: walking around apartment
0532-0542: computing
0543-0579: standing and computing
0580-0581: bathroom
0582-0614: biking
0615-0619: ordering coffee
0620-0852: computing at Stumptown
0853-0860: leaving Stumptown
0861-0868: biking to park
0869-0880: a little more juggling
0881-0888: biking home
0889-0921: cooking
0922-0961: eating, I think
0962-1012: standing and computing, I think
1013-1024: washing dishes, I think
1025-1197: standing and computing
1198-1223: biking to a bar
1224-1295: waiting outside because I misunderstood the arrival time they suggested
1296-1454: talking with friends or dancing, it gets hard to tell at this point

So in total:
computing: 11+143+147+12+35 = 348 = 174 min
standing and computing: 37+51+173 = 261 = 130.5 min
computing at Stumptown: 233 = 116.5 min
coffeeshop logistics: 5+8 = 13 = 6.5 min
bathroom: 2+2+3+10+2+2 = 21 = 10.5 min
biking: 33+8+8+26 = 75 = 37.5 min
walking and juggling and being outside: 72+12 = 84 = 42 min
walking around apartment/cooking/dishwashing: 3+16+2+9+33+12 = 75 = 37.5 min
nap: 63 = 31.5 min
eating dinner: 40 = 20 min
waiting outside bar: 72 = 36 min
in bar: 159 (until the camera cut off at 11:59) = 79.5 min

Total time I spent staring at a computer (it was a real get-things-done day): 421 min = 7 hours. Wow.
Total time I spent walking around and doing in-between things indoors: 44 min, not bad but not great
Biking and being outdoors: 115.5 min = almost 2 hours

... Not sure what to do with this data yet, but dang, that's cool!

hey, that's really cool!
pretty interesting to watch your day go by.
what does the camera look like?- a carnation?

Nah, it's just the iphone camera, so it just looks like a phone in your pocket. It sticks out maybe half an inch, where the camera is. Nobody even noticed.
