Cyanotype on silk threads, 17.5cm x 34cm x 14cm. This piece bears all the marks of trying and finding out - so I learned a lot... The white 'sphere' within is not centred but an asymmetric oval.
The whole thing is, or rather its layers are, a 'blueprint' using sunlight to cyanotype the white 'egg' in the threaded blue body.
