capitalism that the hippies had struggled so hard to change. Other material Examples of other psychedelic art material are tapestry, curtains and stickers, clothing, canvas and other printed artefacts and furniture. Digital age Computer art has allowed for an even greater and more profuse expression of psychedelic vision. Fractal generating software gives an accurate depiction of psychedelic hallucinatory patterns, but even more importantly 2D and 3D graphics software allow for unparalleled freedom of image manipulation. Much of the graphics software seems to permit a direct translation of the psychedelic vision. The "digital revolution" was indeed heralded early on as the "New LSD" by none other than Timothy Leary. The rave movement of the 1990s was a psychedelic renaissance fueled by the advent of newly available digital technologies. The rave movement developed a new graphic art style partially influenced by 1960s psychedelic poster art, but also strongly influenced by graffiti art, and by 1970s advertising art, yet clearly defined by what digital art and computer graphics software and home computers had to offer at the time of creation. Conversely, the convolutional neural network DeepDream finds and enhances patterns in images purely via algorithmic pareidolia. Concurrent to the rave movement, and in key respects integral to it, are the development of new mind-altering drugs, most notably, MDMA (Ecstasy). Ecstasy, like LSD, has had a tangible influence on culture and aesthetics, particularly the aesthetics of rave culture. But MDMA is (arguably) not a real psychedelic, but is described by psychologists as an entactogen. Development of new psychedelics such as 2C-B and related compounds (developed primarily by chemist Alexander Shulgin) which are truly psychedelic has provided a fertile ground for artistic exploration since many of the new psychedelics possess their own unique properties that will affect the artist's vision accordingly. Even as fashions have changed, and art and culture movements have come and gone, certain artists have steadfastly devoted themselves to psychedelia. Well-known examples are Amanda Sage, Alex Grey, and Robert Venosa. These artists have developed unique and distinct styles that while containing elements that are "psychedelic", are clearly artistic expressions that transcend simple categorization. While it is not necessary to use psychedelics to arrive at such a stage of artistic development, serious psychedelic artists are demonstrating that there is tangible technique to obtaining visions, and that technique is the creative use of psychedelic drugs.
