one of the upsides of getting up really early for pre-dawn measurements is the opportunity to set up a camera to capture a time lapse of the sunrise.
this particular morning turned out to revolve more around the movement of clouds, rather than the actual rising sun.
recorded at 4 seconds interval and 30 fps.
last weekend, i was (re)introduced to trad rock climbing by carrie & john. what better region to do that than the blue mountains?
here’s a time lapse video of our first climb at mount piddington, near mt. victoria nsw:
100 min. real time, 10 s interval, 24 fps = 240x speedup.
side note: the smallness and unimpressiveness of climbing nuts and cams is stunning, considering how many people trust their lives to them!
check it out: a section of my time-lapse video of tadpole development was used (with permission) in the following music video for joe reilly’s “amphibians”.
i think this is the most unusual use of anything i have ever made. :)
i can’t get the image of a dancing-digging joseph smith out of my head, so why not post it here…
here’s a clip from “the book of mormon“, a new hit musical by south park makers matt stone and trey parker. in this scene, a young mormon missionary tells the story of prophet joseph smith to ugandan villagers.
i’ve always said that south park songs can easily compete with disney music. this is further proof of my statement.
if you get a chance to see it live on broadway, seize it! i hear it’s incredible on many levels.
stefano padilla used two of my time-lapse videos to create interactive versions. check them out below:
here’s part of the results of an experimental stress physiology class that i took last summer…
in what must have been one of the most open-minded classes i ever took (meaning that we could really influence the topics and experiments), my friend barbara and i studied three aspects of the common wood sorrel (oxalis acetosella): protective leaf movements, photo inhibition and heat resistance.
the following time lapse video shows protective leaf movements, which are a “deliberate” reaction of this little plant to a sudden input of intense, direct sunlight:
on the base of each of three leaflets, turgor controlled pulvinar cells function as a hinge to increase or decrease the leaf angle of the leaflets. such nastic leaf movements can be triggered by a number of exogenous factors such as light (photonasty), temperature (thermonasty) but also by internal
factors.
the concluding course discussion was held as an inofficial “conference of alpine stress physiology”, with poster presentations of all participants.

since facebook aparrently doesn’t allow animated profile pictures, i figured i’d share this here instead:
it’s the animated gif-version of a little “project” i did in 2004/2005, basically a 12-month time-lapse video with awful temporal resolution.
