Is it anything to do with the 1960s Triumph Dove? Road safety?
Yes
No to all
No
Taunting hint:
With all this attention on the doves it is probably a good thing I didn’t mention the lion.
Did the experiment involve human beings (other than the designer)? More than ten? More than 100? More than 1 000?
Was the success of the experiment monetary? Did it generate the designer a lot of publicity?
Was soap involved?
Did this take place at a zoo?

Let’s just say the man was paid for his experiment and it went over well. But I don’t think "a lot of publicity " would be entirely accurate for the designer, however.
