bees flight path

Time lapse of bees in flight.



Dennis Hlynsky is a professor at Rhode Island School of Design. He began filming birds in 2005 on a Flip video camera. What began as a hobby turned into a remarkable study in bird behavior. Hlynsky’s videos capture the raw rhythm of life. They are filled with graceful geometric patterns.


By using a unique process known as extruded time, or layering frame sequences atop one another until the darkest pixels become “tracers”, we are able to see the birds careening across the sky, leaving a discernible trail behind them like ice skates do on ice. Hlynsky uses a Lumix GH2 to capture footage of the birds in flight before turning that into time lapses that are several minutes longer. Once he’s uploaded the footage to his computer, he uses the magic of After Effects to stack the sequence of shots closer together and after hours of editing, the flight paths are finally unveiled. Source:





When I was a child I lived about twelve miles from Bear’s Mill. In the  summer I would occasionally ride my bike down the gravel backroads that led from my home to the mill. I would spend some time sticking my hot feet in the  cool waters and watching the waters fall hypnotically over the dam.


At that time, the mill was still a working mill run by a miller that got to know me and my bike from the frequent trips I made. I had one of the first thin-tired Schwinn bikes with three gears in the county. They were called English bikes at the time. The narrow tires made the bike hard to control on the graveled roads.

I know that 99.9% of the people will never get to Bear’s Mill. It matters little, as it is worth knowing about. That is why I write this. I will probably never get to the pyramids, but I still find them of great and abiding interest.


It is not that Bear’s Mill is one of the great wonders of the world that everyone needs to see. It is simply an historic grist mill in Darke County near Greenville, Ohio, the oldest existing industrial building in the county. It was built in 1849 after settlers had cut the trees out of the Ohio wilderness and grew crops on the newly cleared lands. Before it was put into operation it was purchased from Manning Hart, the builder and contractor, by Gabriel Baer. The stones used for grinding the grains were not hard enough, so Baer traveled to France to purchase high quality milling stones that fit his purpose. The original name was Baer’s Mill, but somehow along the way Bear’s Mill became the referred spelling.

The wood siding on the mill has been in place since 1849. It is a hardwood lap siding made from American Black Walnut and has served the building for over 165 years. In the 1970’s the miller retired and turned the mill over to a non-profit organization called Friends of Bear’s Mill. They still use the mill occasionally to grind a limited amount of grain. The bottom floor now contains a gift shop and an art gallery for local midwest artists to show their works. In 1975 the mill was placed on the National Register of Historic Places. It is both a museum for milling history and a stopping place for tourists who are as fascinated with the mill race and the dam as I was as  a child.


Remnants of the old Indian Toe Path run for half a mile along the creek. The visitors to the mill can take a mild, cooling walk in the summer sizzle where the pioneers and animals walked the hard nine miles to  the settlement at old Fort Green Ville.


An overlook has been built along the creek by the ancient pathway where deer and panthers once roamed and fed.


The steeple of the Darke County Courthouse failed and was replaced in the 1980’s. The old steeple was moved to Bear’s Mill to serve as a memorial to the Viet Nam veterans that died in that horrible war.


The names of the men who died are tagged on the plaque, including one classmate of mine, Gerry Greendyke who never made it home. My classmates and I owe a debt to Gerry and the others that we can never repay. He took our place in the war. He was the one that was killed while we went on to live our own lives. Some came home and many did not. So it is with wars and the young men who fight and die in them.


Away from the memorial, the  woods along the creek remain as they have been for many thousands of years. A cleared path allows the visitors to walk unobstructed in the same spots as ancient mound builders walked ten thousand years ago when the ice sheets were melting and the rivers of Ohio took shape. The birds tweet and the young folk Twitter. And the water, as always, flows forever to the sea.
