The Trap Door co-creator passed away on Friday (25Mar16) after a two-year battle with cancer.

Brain was discovered by television artist Tony Hart and worked on his programme Hartbeat.

He went on to create 1980s children's TV show Trap Door and Stoppit and Tidyup with animator Charlie Mills.

Brain was also working on a programme shortly before his death, according to his son David.

"Dad was a smiley, relaxed person - and a veteran in the industry, who inspired many young animators," he said. "Right up to the end he was making his own series in his spare room. He was four seconds of animation away from finishing a 12-part series he'd been doing, and we're going to try and get someone to finish it off for him. So there's still more to come. He wouldn't have wanted people to know he was in pain, just enjoy his stuff."
