ScienceClic visualizes what you would see falling into a black hole, from the approach and the accretion disc to crossing the horizon, in 15 minutes.
Why Hacker News points people here: Recommended as a great visual explanation of the infall experience, including when spaghettification happens.

Explains what you would see falling into a black hole.
Awesome. Also, see this great YouTube video of what you would see if you fell into a Black Hole. Is also has a very good explanations of what you are seeing: this video
“According to this video, the spaghettification doesn't happen until the last few seconds/minutes”
Spaghettification only occurs near the singularity.
According to this video, the spaghettification doesn't happen until the last few seconds/minutes, when you're close to the singularity. this video
Shows you still see your own legs crossing the horizon.
While I prefer "event horizon" over "singularity", part of the reason I blogged about this distinction years ago was that the event horizon always seems to be ahead of you as you fall in to a black hole*. My blog posts didn't age all that well, and I've learned to be a little more sceptical about the speed of technological change, just as the political events over the intervening years have made me more aware of how fast political realities can change: link and link * at least until the rate of change of curvature gets so high you're spaghetti, you're (approximately) co-moving with the light from your own body. This means that when you cross the event horizon, you still see your own legs, even though the space the light is in is moving towards the singularity faster than the light itself moves through that space: this video
