There is an interesting series of 3 videos by vihart on the Fibonacci sequence and plants [1] that is done very well. It may interest you if you found the OP video interesting.
Can anybody figure out the year?
Around 1980 seems right. This was an Australian science show for children. Loved that show.
Now there is a children's show that doesn't talk down to the children.
