Fors was a member of the legendary Volumen I (Volume I), and participated in their first exhibition in 1981 with an installation. During the Eighties, Fors produced installations that were ground-breaking for the Cuban context, and these are perhaps his best known works. Working with natural materials, such as leaves, was a challenge at a time, when something like that was not generally considered art in his country. His installations and other works of this period leaned towards a more conceptual approach. Instead of the universal and trite symbols of time, Fors chose decadence, as a metaphoric image through his dried leaves accumulations to render the passage of time. This was the backbone of his first solo exhibition titled Acumulaciones (Accumulations) in 1983. In those early years, he was engaged in exploring the concept of the passage of time and the evocative power of memory, and these installations proved to be the ideal visual solutions.

His work has always revolved around memory in one way or another, either through his photographs or his installations. When he began to exhibit in the late Seventies, photography was far from being his technique of choice. He was trained as a painter and his excursions into photography began when he had to photograph some of his installations. He liked the effect and from then on photography became part of the creative process for him.
