The 'Event' considered here is my 'abduction' as a child by my parents out of the Netherlands as part of the post war European migration to Australia in the 1950s. The migrant exists in many ways in-between cultures and this also holds for the migrant child. This event created a traumatic split in me as an eight year old boy. It was one that occurred to many children of migrants who left Europe post WWII. The migration in turn engaged with an unspoken racist complicity with Australia's 'White Australia Policy'. The 'white' Dutch were a good fit for this migration and thus the focus here applies to both 1950s Australia and the Netherlands. This article deals with how I expressed the two aspects of dislocation and racism made evident by this event through my art in a collaborative exhibition The Unwanted Land (see Figure 1). As this art is primarily visual, I have included a photo gallery of 28 images at the end of this text to reference and support this discussion.

There is no conclusive evidence of any nonhuman animal using the sun as part of its predation strategy. Here, we show that the world's largest predatory fish-the white shark (Carcharodon carcharias)-exploits the sun when approaching baits by positioning the sun directly behind them. On sunny days, sharks reversed their direction of approach along an east-west axis from morning to afternoon but had uniformly distributed approach directions during overcast conditions. These results show that white sharks have sufficient behavioral flexibility to exploit fluctuating environmental features when predating. This sun-tracking predation strategy has a number of potential functional roles, including improvement of prey detection, avoidance of retinal overstimulation, and predator concealment.
