The Time Machine @ Printed Matter, Chelsea. Click to enlarge

As long as the red button is held, the Time Machine ^TM will print a receipt. The longer the button is pressed, the more extensive the printout becomes.

The Time Machine ^TM Network was launched in 2013 by artist Malte Bartsch. As part of the project, 69 time machines have been positioned in a total of 4 countries.

A total of 25,496 individual artistic works (receipts) were created in which the button was pressed for 157,566 seconds.

Each installation is:
thermal printer, button, person, time, 25 cm × 31 cm × 13 cm, 2013 – ongoing.

The machines are available here:
