Return of the Attractors!

Thursday, March 5th, 2009 | Building Things, images, Processing | 1 Comment

I recently received an email asking for more information and code about my attractor experiments in Processing. I initially thought I’d write a little tutorial but as I was searching around I found a great site with code examples by Dave Bollinger. His experiments do almost exactly what I have been doing but his examples are probably better programmed than mine and thus simpler to understand, you can find a load of his work here. And a nice attractor here.

While I was playing with my own attractor I got some nice new images by concentrating the attractors on the x axis:


orbs on the x axis

orbs aligned on the x axis

and a surprising set of moth wings:

Attractors give you wings!

Attractors give you wings!

I also did some non-real-time animations in which the attractors are moved slightly each frame which creates ever-shifting fields of attraction and repulsion which = pretty!

All best,

Leafcutter John.

Animated Graphic Score Played by York University Music Students

Wednesday, February 25th, 2009 | Graphic Scores, Processing | 10 Comments


This is a recording of the first run-through of my score with students from York Uni’s Music Department. I love how they played the piece and it’s even more amazing considering this was the first time they had laid eyes on it. The result is surprisingly coherent given that there are 11 people playing.

Recorded with a little stereo mic in the middle of the room so the instrument balance is way off I’m afraid. The piece will be performed by an augmented version of this ensemble as part of the York Spring Music Festival in May 2009.

Many thanks to the musicians for their enthusiasm and for allowing me to put up a rehersal, and thanks to Simon for all his organising!

Performed by: 

  • Violin – Hannah Wells
  • Viola – Vic Bernath
  • Cello – Chris Mullender
  • Double Bass – Vanessa McWilliam
  • Double Bass – Gareth Taitt
  • Oboe – Des Clarke 
  • Flute – Megan Fennell
  • Flute – Ellie Haines
  • French Horn – Benjamin Gait
  • Piano – Dave Morecroft
  • Voice – Anna Goldbeck-Wood

Animated Graphic Score as played by Kammer Klang Quartet!

Wednesday, January 28th, 2009 | Graphic Scores, Live Shows, Processing | 11 Comments

I’m really happy about how the premiere of the score piece turned out! I think the Kammer Klang Quartet did an excellent job with it. It was inspiring to see how each individual dealt with the notation in a different way while still maintaing some kind of group integrity. It seemed like the whole thing went down well with the audience too, perhaps because they could see the score projected as it was played. I’m going to work on a second score as soon as I finish off the things I have on my plate at the moment, perhaps now the rules have been established it might be fun to bend them a little.

I must thank Lucy for putting on a great night and Dave for his dedication to the sound! Also my thanks to Mr Leo – Simon Bookish who’s criticism and suggestions were invaluable in the making of this piece. 

The Kammer Klang Quartet were:

Kammer Klang is a monthly event and I highly recommend it!

Finally a note about the video – The audio sync is not perfect, this is a video issue and nothing to do with the fine playing of the Quartet! The sound was recorded on my little Sony D-50 and my Soundman Binaural mic’s laid on a table so it’s not fantstic. Good enough though to illustrate the evening’s events.

All the best,

Leafcutter John.
