Notes: This calculator was clearly not designed to be usable, it was designed to be peculiar and succeeds quite well.

The display in inverse and very sleek. All numeric buttons are in one row and all other functions are in one row, including the decimal point with the "="-key somewhere in the middle!

This was my 2006 birthday present from Jan Hurstjes. Thanks Jan!
