Can't really take credit for these - I picked up this adorable little Rebutia heliosa (aka a tiny cactus) at the same time I got the Euphorbia obesa/Big Green Ball Plant and it bloomed the next day. Maybe out of joy and happiness at finding a loving home?
I'm not big on cacti, but I love small plants....so in the case of Rebutias their small-ness tends to win out over their cacti-ness. Plus I feel more secure that in case the plant decided to get uppity and poke me I will be able to defend myself.
And some more flower shots:
