Beginnings of Something Cool

I got a flash sound trigger for my birthday last week. Spent a few hours configuring it tonight and got one cool shot at the end of the night. It takes a lot more work than expected to get the timing right. You can see the bullet that shot the bottle to the right. More to come. Explanation later.
