Jale, which is Persian for morning dew or dewdrop, is a transforming patchwork by Heike Sperber, a MediaTechnology student from the University of Leiden. The patchwork uses a temperature sensor to trigger a change of seasons, so that when it becomes cold the patchwork shows the blue snowflake and when it becomes warmer the sun motive reappears.


The quilting technique of Jale is known as English Paper Piecing. Heike used a servo motor with nylon fishing wire attached to the corners of the patchwork to turn the fabric flaps.

Jale was part of the exhibition Pretty Smart Textiles which was on show in Holland earlier this year.
