Data art – 2011-2015—Thursday Island tide gauge
Cause why not? I like the idea that the data produced by this unassuming automatic tide gauge on Thursday Island can be used for art. I had to extract the date and the value from the single column of data (example 120520110710 2.558) I used to use open refine for this but it is easy enough in excel these days to pull out the sections.
I could only use a section of days as it gets into the 1000’s of frames and weighs everything down. I kept this very simple the tide is represented in 3 ways – the circle the water height and the volume of the ocean – I figured if the tide was high the waves volume should drop and if low the volume increase.
The ebbing is perfect for data art – the natural variance you get in the data is something that would be hard to animate and have it look realistic. The fluctuations from the standard give it some variance that make it interesting.. Higher than usual tides and patterns between the days.
Data art – SoE2015 Southern Oscillation Index
Another time series data driven animation. This time using the historic records of the SOI (Southern Oscillation Index) since 1876 as the input. Because the SOI is a dance between positive and negative it was challenging to wrangle into some form of data art. Originally I explored what visually represents the aspects of positive and negative – batteries, yin yang, hot/cold but when you apply it to a single object (rather than something that is time based) the data just produces oscillations without a time perspective.
This dataset only has 4 columns of data so it was easy to work with YEAR, MONTH, SOI, SIX MONTH MEAN. I had to scale the values of the SOI as the max ranges seem to be around 50 which doesn’t highlight the fluctuations that well.
Due to the nature of the SOI being negative it also was perfect to control the volume of the wind as it goes negative and positive when the SOI is positive it turns the volume up. It’s interesting to look at a dataset and see the values as potential for art rather than static values. Inputs that require array values are perfect [RGB, audio, position…] you can plot the data in unique ways that might highlight a pattern that isn’t obvious.
