Not me ! ....

From what I can make out it looks like a succulent? Which one I don't know.

Looks like a goldfish plant Neomaricus gracilis, I might have that wrong but I've got one in my garden with the latin name. Looks like it might want stronger light and more humidity. Thats my guess, hope it helps.

Nematanthus gregarious, goldfish plant. There is another looks like this as well, I don't know that name. THat one is more compact growth habit like this.

is this indoor or outdoor ??

Indoor, probably zone 9-10 if outdoor, No frosts.
