Do you like this?
Both pics show the same plant, African Milk Tree (Euphorbia trigona). They love it indoors, and grow quickly to 4' - 6' tall, even in containers. Looks a lot like a cactus, doesn't it?
Honestly, I can't think of any cactus that thrive in containers like that, if you want a dramatic "sorta" cactus, pick one up, I have one in my front yard that's growing like a weed. It probably won't survive next winter.
