Physiograms
I hesitate to call these art. But I'm not sure where else to post this.
I have a number of pages, and many photographs, about "swinging light + swinging camera" pictures: http://www.barry.pearson.name/articles/physiograms/ The originals, which I took when at school over 40 years ago, may be of interest: http://www.barry.pearson.name/photog...ysiograms0.htm I have recently added various filters and layer styles to many of these: http://www.barry.pearson.name/photog...hysiograms.htm I have also added some web-effects, using Java applets (not mine) to some of these, for example: http://www.barry.pearson.name/photog...s_22_10e_3.htm http://www.barry.pearson.name/photog...s_20_24c_3.htm Other people are also doing physiograms: http://www.barry.pearson.name/articl...references.htm Enjoy! -- Barry Pearson http://www.barry.pearson.name/photography/ http://www.birdsandanimals.info/ |

He used sounds of different frequencies to vibrate a mirror, and reflected a beam of light off it to trace patterns. Lissajous' setup was similar to the apparatus which is used today to project laser light shows, so you might try in any group about the band Pink Floyd. Or electronics/physics/engineering forums. They might be interested in them as art. |

I have a section of the website that talks about Lissajous figures: http://www.barry.pearson.name/articl...ams/shapes.htm Normally, the term refers to two linear harmonic motions at right angles. Some of the photographs are like that. The spreadsheet provided can draw a whole variety of Lissajous figures. Others are based on twin-elliptical effects. These are not normally refered to as Lissajous figures. The spreadsheet can draw those too. [snip] Or electronics/physics/engineering forums. They might be interested in them as art. Interesting idea! Thanks. -- Barry Pearson http://www.barry.pearson.name/photography/ http://www.birdsandanimals.info/ |
