2C-T-7 always gave me a combination of all of the classic visual distortions at once, and they were always intensified to a hilarious degree.
Swirling, rotating, fractal rainbows cover every surface. Everything shines, sparkles, and is covered with glitter. There's glitter floating through the air. Laser beams shoot out of lights and windows and mirrors and water. Anything that moves leaves composite images (trails) behind that take up to 30 seconds to fade away.
I sat on a sidewalk once and could watch the cars coming down a perpendicular street, from one end of my field of vision until they drove past the other end of my field of vision... and the cars would leave behind a dancing metallic rainbow colored stream of after-images of the car's tail end, so that it forms one 300ft long rainbow dragon... and as the car's front gets closer I realize it's an anthropomorphic face, and the grill gives me a huge Cheshire Cat smile and one of the headlights winks! And then as it speeds past me, its hundreds of feet long rainbow dragon trail slowly follows behind it, spitting pixie dust all over the road instead of exhaust.
2C-T-2 has visuals much more like 2C-B, 2C-C, etc.
