In 2012, at the IFA booth of Deutsche Telekom, Dan Perjovschi worked every day for a couple of hours on a large black wall with chalk. 'Chalk Reality (digital flair)' changed over the time like a school board, drawings were wiped out, others were overdrawn and the public, literally hundreds of visitors, was witness to the artistic process. 'The Low Tech in High Tech, The IFA Berlin Notebook 2012' contains a selection of the drawings.
