A.3 Raindrops

First, notice that the raindrops seem to form clusters of raindrops of varying sizes. Frequently there are raindrops of the five possible sizes clustered together. Perhaps joining them in order of size might help. It doesn't in all cases, though.

Instead, join each raindrop to the nearest raindrop that is smaller than it, if there is one. (Raindrops of the smallest size actually all get connected to by a larger raindrop, but they don't produce any additional connections of their own, since there are no smaller ones to connect to.) Make the connections by joining the centres with a line. Measure nearness by the distance between the edges of the raindrops (not the centres).

The result should look something like this:

The shapes formed produce letters. With a little imagination, the text reads "FALLING ON MY HEAD MOVIE".

Remember that the title is "Raindrops". The song Raindrops Keep Fallin' On My Head appears in a few movies, but it was written for the movie Butch Cassidy and the Sundance Kid.

The answer is BUTCHCASSIDYANDTHESUNDANCEKID.
