UPDATE: Videos have been moved to Vimeo.
I just noticed that I got linked to from Create Digital Motion, a blog about digital video production and computer animation. Cheers guys! However, the post says that there is "more at [my] personal site" and.. well, there isn't. Or wasn't, until now.
The post is about Radiohead's "House of Cards" video which has been getting a lot of coverage on t'interwebs this week. I'll spare the technical details as you're almost certainly familiar with them by now (if not, have a look at this post). My two attempts (so far) are below, along with a little info about how they were made. You can view both the videos in higher quality by clicking through to YouTube Vimeo.
The first set of experiments is based on a really simple particle system. The x, y and z co-ordinates of each point in the data cloud are turned into a particle, which is then "bounced" off a hard surface using very basic physics. The position of each particle of each frame in the video is calculated the correct number of times to produce the animation effect. By bouncing the particles at different angles relative to the "camera," appearance of the bouncing particle cloud can be changed, creating some unusual visuals. The next section of the video is created by duplicating each point three times, to create three versions of Thom's head. Finally, every particle is given a random velocity, creating an "explosion" effect which again is modelled as a large number of bouncing physical objects.
The second video is simpler: no physical simulation, just a set of lines. Every point is connected to another point with a line. The number of points slowly increases over the video, so Thom's face slowly appears from randomness.
I've put some higher-quality stills from the videos on my Flickr account.
