Helman Heilahdus ("A Sway of the Hem") delights passengers and commuters at Helsinki Airport railway station. The panoramic two-part work by artist Aarne Jämsä is located in the platform area of the railway station, 45 metres below ground.

The work depicts pleated fabric, lace and sequins. The sheets have been mounted on rock on both sides of the platform.

Jämsä's original drawing was done in coloured pencil, and the forms have been modified by computer to the new measurements and printed on aluminium sheets. The end result is about 690 square metres of meticulous drawing. The work is over seven metres high and it is one of the largest works of art in Finland.
