A pendulum is a weight suspended from a pivot so that it can swing freely. When a pendulum is displaced sideways from its restingequilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position. When released, the restoring force combined with the pendulum's mass causes it tooscillate about the equilibrium position, swinging back and forth. The time for one complete cycle, a left swing and a right swing, is called theperiod. The period depends on the length of the pendulum and also on the amplitude of the oscillation. However, if the amplitude is small, the period is almost independent of the amplitude.

A beautiful set of posters that uses installation and Spirograph art to create a visual story. I like the use of craft and detail and personally by already trying to get our own spirographs draw it's a very crafty and beautiful spirograps that they got.

A project done by Danny & Mirela of tracing parabolic speakers was an interesting investigation of sound and applied mathematics.
Since we’re also doing another project that’s related to parabolic speakers, we figured let’s do this one together - and simultaneously work on the Harmonograph-project too, see pictures below for the book I showed in class.
In the first project we’ll make parabolic speakers (probably 2) that ‘follow’ the people walking around in the installation. So, beams of audio will be directed to the person, and he/she will hear it while other people (not standing in the beam) hear much less - if anything.
In the Touch Harmonographs project, we’ll try to make an ‘environment’ where people can create harmonographs on the walls (floor?) by drawing a line with their fingers/hand. A corresponding sound will be created.
Week 1. Try to make some harmonograph graphics (hooked to mouse dragged). Upload a screen-capture.
Week 2. Make some sounds correspond with the graphics. (Octave, Chords, see harmonograph booklet). Finish watching Theo’s VideoManager Class Tutorial & start writing classes ourselves.
Week 3. Begin making tools for a touchscreen (Ir camera, Ir lights, surface?). Decide whether to let the walls be as they are - or to put something there to deform the projections. Reserve a beamer (Rental)!
Week 4. Finishing up the code - testing & trying to make it crash, etc. etc.
Week 5. Making the complete test setup. Fix last problems that occur.
Week 6. Complete project.
And a video: Harmonograph tryouts in O_F - screencapture
Tracking Parabolic Speakers:
week 1 - Looking up examples of parabolic speakers - tutorials maybe? First dish tests (speaker + dish & one speaker in tube - picture + video coming soon!)
week 2 - See how to make the arduino + 2 servo’s work with O_F. How to make 2 arduino’s work at the same time? Look for steppermotor-chips. Post more stuff on the blog - pictures/video/progress.
week 3 - Start writing code for face/blob/? -detection - how to track people the most efficient way, etc.
week 4 - Make first test-setting - complete writing the code & assembling servo’s + arduino(’s). Final decision which audio to use.
week 5 - Finishing up - testing.
week 6 - Complete project

When I first started talking with Troy about the future of Tamarillo and his plans of staying in Leeds, living with Lewis and creating music for the band in order to kick it off. I looked at the band and it didn't have much going on. The visual design was made by Lewis and was used as their identity.
