Between 12.1.2017 and 17.12.2017 I sat on an alder stub in Kaivopuisto park in Helsinki altogether 100 times. These visits were recorded on video and edited into With an Alder in Kaivopuisto (Spring) (3h 49 min 23 sec) and With an Alder in Kaivopuisto (Autumn) (3 h 54 min 12 sec). For presentation purposes a shorter version is edited with one-minute images of each session, With an Alder in Kaivopuisto (1h 40 min 10 sec), included here with very much reduced file size.
