Mole-Rat is an EMF audio device which released in September 2015. This audio device allows users to discover the electromagnetic fields in the living environment.

Delay Line Memory (2014) is an impromptu live audio-visual performance, interplay between man and machine, in an attempt to find a common language in electronic sound, rhythm, and color. Patterns are temporarily stored within a 'delay line memory', a form of sequential access memory that was used for early computing. By delaying the data signal, it is effectively memorized for a given period of time. This work could be performed as a solo by Bas van Koolwijk (Electronics & visuals) or in combination with drums by Gert-Jan Prins. In 2016, van Koolwijk released video demos on his website DLM.

The released SYNCHRONATOR AV device in 2009 transforms the audio (3 inputs on each of the primary color channels of the video signal) into a composite video signal. Later in 2018, they developed an HD version by updating the connection to a beamer, flat-screen TV, or capture card with HDMI signal.

In his solo exhibition in 2007, he presented Red Flag and Silver as the high-resolution version with projection. After in 2014, he created a live set version Curvilinear for the projection within the Sphæræ dome, which he performed at the GOGBOT Festival (Enschede. the Nederlands). Furthermore, he released a 12 minutes video with the same title and screening at AxS Festival (Pasadena CA, USA).

The first video of this series Red Flag is released in 2005 and is produced with software applications (Max/MSP) that were developed for the live performance FDBCK/AV. The 'flagging' seen in this video is of a digital nature entirely, but its logic is based on analog video processing. The same logic applies to the computations by which FDBCK/AV creates a feedback control circuit between audio and video signals. This series includes three main abstract videos: Red Flag, Silver (2005), and Curvilinear (2014).

SYNCHRONATOR is a video and audio research project initiated by Bas van Koolwijk and Gert-Jan Prins. They met and saw each other's work while they were presenting their own audio-visual performance at Impakt Festival in Amsterdam (2005). This encounter let them find many similarities in their work, also the problem they both have. So they started to develop a device together with the residency project at Impakt's laboratory (Utrecht, the Netherlands) in June 2006. Bas van Koolwijk works mainly with digital equipment also convert the video signal to audio signal, while Gert-Jan Prins works with analog techniques and transfer the audio signal to the video signal shown on the CRT TV set. The major problem they met is the complicated or distorted video and audio signals cannot be recorded on tape or accepted by video equipment like a projector. After six weeks, they developed a prototype of SYNCHRONATOR that allows them to synchronize every form of data input and then turn it into an official video signal.

With the same principle, Van Koolwijk later produced another abstract video FIVE (2002) as part of a series of abstract video compositions.

His work has appeared at media festivals worldwide since 2000, for instance at Impakt Festival, GOGBOT Festival, Ars Electronica, Elektra Festival and Netmage. Some of his early video works are distributed at LIMA, the Netherlands. One of the series TST was selected for the Digital Canon (1960-2000) research project.

TST (2000) is a series of abstract video compositions based on video disturbances, which consists of minimalistic color lines and blocks, and with flickering movement. Van Koolwijk started with experimenting analog video technologies, by using the electronic signal of the CRT monitor to produce abstract images. Then he captured these image materials into the computer and composited all the materials. Meanwhile, as he would like to monitor the visual and acoustic, he split the video signal to one CRT and another through an audio mixer converted into audio. In the end, he recorded the composited audio and served as the video soundtrack. This series contains three video compositions: TST 02, TST 03, TST 04.

Bas van Koolwijk (born in Nijmegen in 1966) is a Dutch video and audio artist who lives and works in Utrecht, the Netherlands. He has studied painting and received the degree from the Hogeschool door de Kunsten Utrecht. Since 1998, he started using video for installation, then he found out that he was interested more in the characteristics of the images and sounds. He thought these interference and noises seem to have their own visual language. With this thought, he connected back to his painting's formalistic approach that he could experiment and composite with these abstract elements of image and sound, also abandoned the narrative stories.
