A needle cuts grooves into a rotating candle, recording sound; a laser and diode read the sound; a moving tea light heats the candle and gradually erases the recorded grooves. This is part two in a series of recording devices that complete the memory cycle by remembering to forget.

Realized in 2 days during ArtHackDay Berlin –afterglow – at transmediale in winter 2014.
