the lorenz attractor

lab :: with papervision3D

papervision3D lorenz attractor

we were discussing recursive algorithms and chaos theory at work yesterday. when one of the chemistry professors brought up the lorenz attractor. he was trying to draw one on the white board for about 10 minutes until i decided it would be easier to draw in flash, lol!

after a quick conversation w/ andy zupko about the new Line3D object, and my new CanvasView3D component for papervision, i made a sweet lorenz attractor! 

the algorithm is super simple:

x1 = x0 + h * a * (y0 - x0);
y1 = y0 + h * (x0 * (b - z0) - y0);
z1 = z0 + h * (x0 * y0 - c * z0);

pirate themed wedding

random :: on halloween

pirate nina and xero

this year's halloween was a bit different. our friends opie and jessie had a pirate themed wedding! so deciding was to be this time around was pretty obvious. they had the ceremony and the reception at the same hall in pittsburgh, but since we were late as usual, we missed the first part. but they didn't seem to mind, since the actual wedding part took about 10 minutes! LOL! 

the reception was crazy! all the guests were dressed as pirates...

so my parents, nina, and i went to the rock & roll hall of fame in cleveland ohio. my dad had a few vacation days, so he wanted to take a trip. i have been to the hall a few times prior, but they have such a flux of different memorabilia... so it’s never the same place. this time the featured exhibits were the doors, the clash, and warped tour. the clash exhibit had a ton of old outfits the band wore, along with old instruments, tour photos, and flyers.

butterfly stuck in a lilly

random :: art floria

monarch buttery fly stuck in a lilly

it has been a great year for flowers. thus it has been a great year for floral photography. i dont know why, but after my experience with the african violets, i have been into art flora a lot more. my mother's green thumb grew some beautiful golden lillys right by their porch. i took a few snaps, then went inside. i returned a few minutes later with a clean memory stick only to discover a monarch butterfly in the lilly i was just shooting.
