Ratz (Simon Matthews) was a CPC coder and graphic artist, member of STS and frequent contributor to BTL.
His best-known work is the Ratz/Wulf Demo 3, rated as perhaps the best British demo ever released. He began work on a megademo called Eclipse, but the project was later shelved and incorporated into Systeme D's still unreleased Palatine demo.
He appeared in the BTL 4 Reservoir Dogs intro as "Nice Guy Eddie".
