When a young woman is overcome by panic, her mind transforms into a terrifying, dark world. She flees a devastating thundercloud that is hot on her heels and must face her deepest fears to escape this nightmare.

Thunderhead (2025) is the avant-garde animation debut of visual artist Una Jongenelis. The film combines 2D- and 3D-animation techniques to emphasize the different worlds that can be experienced while enduring a panic attack.
Synopsis:
A young woman is overwhelmed by a panic attack. In an attempt to calm herself, her mind transforms into a dark place where all logic seems to have vanished. The nightmare culminates when her fears materialize in a devastating cloud that is hot on her heels. When she sinks into a miserable downward spiral of negative thoughts she realizes that she needs to face her deepest fears to escape.
Thunderhead will have its World Première at International Filmfestival Rotterdam (IFFR) in January 2026!

The 2nd Volume of ‘Una’s Book Project’ is here! DO YOU SEE THAT TOO?! is 48 stencilprinted pages telling a story of struggle with ink and paper.
The book starts with a rewriting of Anne Carson’s ‘God’s list of liquids’ (from ‘Glass Ironay and God’ 1995) as a liquid thread throughout the publication, spilling into the shapeshifting main character’s perspective, fighting over the authority of creation.
This book was made, printed and presented in one day, on March 22nd 2025 at Woonwerkpand Tetterode. This volume is curated by Una Jongenelis and made together with Romy Day Winkel, Igor Jongenelis, Chris Sleiman, Mikel van Gelderen, Norbert Storm, David Kloosterboer and G.C. Heemskerk.
Una’s Book Project is an ongoing experiment of collaborative drawing and book making. The book was printed by Sander from the Stencilzolder.
