Barry Roux, Oscar Pistorius' defence lawyer, asked the athlete to remove his prosthetics and to show the court what he looks like without his stumps.
He had previously been wearing a suit, but after a short break, re-entered the court room in a hoodie and shorts.
#OscarPistorius pointing to OP on his stumps, Roux says this is the man frightened at 3 in the morning.
He said to the court that the man they were looking at, standing on his stumps, was the man who was scared for his life at 3am, and thought an intruder was in his home.
Barry Roux, defending for Oscar Pistorius in his sentencing trial, has told the court that Pistorius has already paid physically, emotionally, and socially since he made the decision to fire his gun.
He must "live with this for the rest of his life", he can never resume his career, and will punish himself "far more than any court" can, Roux said.
Barry Roux is arguing that Pistorius should not be given the mandatory sentence of 15 years, due to mitigating circumstances.
The defending lawyer for Oscar Pistorius has said that there is a "misconception" that Oscar wanted to kill his girlfriend Reeva Steenkamp.
Barry Roux, defending for the athlete, said that there are "substantial and compelling circumstances" to pass a sentence that deviates from the mandatory 15 years.
Oscar Pistorius was a man on his stumps who did not want to kill his girlfriend, and was in fear of his life, he said, and therefore his sentence should be reduced.
#OscarPistorius roux says too many misconceptions about OP. Must see him as a 1.5m man standing on stumps at 3 am. Scared
He also referred to a case where a father mistakenly shot his own daughter, thinking she was an intruder. The man was not prosecuted.

Barry Steenkamp has told a court in South Africa he "didn't know" about his daughter's relationship with Oscar Pistorius.
"I didn't know about it, no," he said.
"I don't think the time was right for her to tell me, otherwise she would have told me."
Barry Steenkamp has told a court he and his wife June forgive Oscar Pistorius for killing his daughter, but he must pay for his crime.
Mr Steenkamp added that he would like to talk to Pistorius one day.
"June (Reeva's mother) is a Christian, so am I but I don't really go to church. June has forgiven. She feels it's right in her heart to forgive Oscar," he said.
"But...forgiving like that, it still does not exonerate you from the crime that you committed. He has to pay for that.
"It's been very difficult for me to forgive. But I feel the same, that Oscar has to pay for what he did. He has to pay for it. And that's all I can say.
"Most probably the time will come when I want to talk to Oscar, in private, not now, at a later stage, I would like to talk to him, yes."
The father of Reeva Steenkamp has described in court the moment he found out his daughter had died.
"I was at work. I got a phone call from June", said Barry Steenkamp.
"I couldn't really understand what she was so upset about. (She was) screaming and shouting. At first I thought one of our animals had got killed or something. She said 'come home immediately, come home'.
"I dropped everything. On my way home I tried to fathom what she had tried to tell me but then I realised she'd mentioned Reeva.
"Driving home I realised more and more, Reeva's been killed. It hit me then.
"It's like it happened yesterday. Thank god we had a friend of us staying at the house. He was trying to comfort June."
The father of Reeva Steenkamp has said his family were given notice on their house within two weeks of her death after his landlady learned of their financial situation through the media.
"With Reeva's passing the landlady had found out that I was virtually bankrupt and within two weeks of Reeva's death she gave us notice on the house," said Barry Steenkamp.
"We'd never been behind on our rent or anything. But she gave us notice because of what she read in the newspapers.
"It was so distasteful that we decided to relocate immediately"
