Remember everyone reacts differently, but here's what various things do to me visually (in no particular order):
Morning glory seeds
Minor OEV's - trails (esp. with a light object moving across a dark background), color shifts, certain things may seem MUCH brighter than they really are (like a metal spoon relfecting light), and slight movement/crawling of surfaces (subtle, but very realistic looking).
Amazing CEV's. Very colorful, realistic, detailed and strange! Not just patterns, but scenes, people and entities. Sort of difficult to describe.
LSD
Unfortunately the 3 times I have taken LSD it has not been in a high enough dosage to have a full on trip. I did get minor visuals all three times, but I was expecting so much more. I noticed that surfaces were crawling / melting / morphing - very cool. Some objects looked very distorted as far as distance from me, height, width and depth. CEV's were very
neat :D. Very geometric and defined.
2C-T-2
Probably the
most visual substance I've sampled. People had 4 arms, behind my eyelids existed a colorful psychedelic firestorm, everything that moved left long trails, etc. There was some mental changes for me, but so far this would be the one I'd say that would be closest to "visuals with no mind-fuck."
2C-I
I've only tried it once and was very dissapointed. I had some visuals and an uncomfortable body-load.
4-HO-DiPT
Colorful patterning and wavy movement. Cool CEV's. Visuals definately are not the main attraction (the body high and mental effects are so much more noticable, I don't even really care about the visuals).
4-HO-MiPT
Ah, Miprocin. One of, if not the best drug I've tried. Crazy visuals, great body high, and a wonderfully intense mental trip. The visuals are best outside at night. I see very detailed, colorful patterns across my entire field of vision, objects seem sort of fuzzy around the edges (like it's vibrating really fast), people's faces have changed completely (people that were in their teens-20's looked like they were 50 or 60 years old!), plants seem to look indescribably strange, and so much more,
5-MeO-DMT
I've never had a breakthrough on this one

. I did get some minor visual distortions like movement trails.
5-MeO-AMT
This one's quite strange. Every time I've taken this one, it's been from the same batch. Some time's I'll have really strong visuals (strong ghost-like trails,
insane CEV's like extremely detailed demons writhing in fratalated blood that morph into dragons and female warriors!), and other times almost no visuals. 5-MeO-AMT headaches suck.
5-MeO-DiPT
I've taken Foxy once. It was a low dose, and I actually liked it! I had no ill side-effects - but it wasn't a strong trip either. Not too much visually speaking.
Cannabis
Weed gives me visuals. It always has. Mostly slight movement trails and colorful patterns on surfaces.
Harmaline
I wasn't really expecting this one to be visual by itself. It was nothing amazing, but it made me see movement trails and everything sort-of looked clearer / sharper.
Nitrous Oxide
Nitrous is very visual for me, even without any other drugs. For as long as I can feel the wonderful nitrous feeling I see strange, repetitious, colorful patterns across my entire field of vision. I can never manage to close my eyes though...I just hold completely still and let the glory overcome me.
DXM
The only OEV's I've had with DXM that didn't depend on darkness were strange spacial distortions. The CEV's are awesome, movies in your mind.
Ketamine
Although my visual perception is not really that important or interesting to me in a K-hole, I have noticed spacial distortions like DXM. A few times, it seemed like my whole visual field was slightly
sideways, now that was weird.
MDMA / MDA / MDEA
I grouped these together since I've never had a pure source. Not very visual for the most part, but I can recall one particular vision (from a suspected MDA / caffeine pill). I was looking down a corridor and I was watching people talk. I looked at a guy's face. It seemed demonic and distorted. Then the guy turned his head, and I realised I was not looking at his face before when I saw the demon face, it was the back of his head. This startled me as I was not used to seeing things like this while rolling.
