I wake up having had a nightmare, but it is really a memory of a real event that was playing out in my dreams. In the memory, I am seeing one of my PhD students get publicly attacked by a senior professor (who is also someone I respect and in some ways depend on). I run through all the ways I could have acted differently in that moment. I visualise myself standing up in front of the room and hitting back. It plays and plays, until I manage to have breakfast. By lunchtime, though, I am lost in the flow of an article I'm trying to finish before holiday. As a visual contribution to the article, after lunch I experiment with making a satellite image (one that features a current of 'Saharan Dust' moving northward over the Mediterranean) into a 'thaumatrope': an analog, double sided, spinning device that creates an optical 'illusion' of blurred borders, animated shadows, and miscible surfaces. It feels good playing with a satellite image not on a digital screen (as I overwhelmingly do in open-weather) and rather in tactile, DIY form, using a tool that is reminiscent of children's games. For me, the thaumatrope creates a kind of optical 'irritation' of moving forms, nebulous shapes and shadows, and disappearing or fading-out land and sea edges. It also seems to 'agitate' the cartographic orientation devices that we use when we see the coastline of North Africa and the 'boot' of Italy. Writing of images of the monsoon, Harshavardhan Bhat writes, "Satellite images empowered by spectroradiometer science and international coalitions begin to not just inform the science of the state but the imaginary that the monsoon unifies the entity called South Asia as part of a planetary system... This is a gift to political theory as the monsoon then becomes this technology through which the planetary infrastructure of surveillance and governance slowly unfold, silencing the complex work of the air of the monsoon" (2022: 240). Does the thaumatrope help to destabilise the 'unified entity' of the Scirocco or Jugo wind that brings 'Saharan Dust' to Europe? Does seeing a satellite image flicker and blur between channels demonstrate something about the 'slippages' of materials and elements in satellite imagery, inviting us to see beyond the 'optical ontology of pixels'? In contrast to a regional 'event', can we recognise something about the 'complex work of the air'?
