The Dutch Tax Authorities’ computational department has it’s base in Apeldoorn. It’s location, the Walterboscomplex, was radically renovated and renewed between 2004 and 2007.

The façade of the new towers H and E are etirely made out of glass. To have a better climatecontrol inside, the architect provided for ‘Saturn-rings’ outside the building. Additional screenprints were needed on the glass to reach the right % of sunlight filtering.

Writing data on a harddisk seemes analogue to the the shapes made by certain beetles underneath treebark.

Cellstructures, insects and other biological shapes made out of geometrical elements.
