As someone who has used, and watched my kids use, pitching machines, I like the idea of the pitch alert systems. Part of hitting is timing the pitcher's windup (or stretch) to get ready for the arrival of the ball.
I like the pest zapper, too, as long as it doesn't hurt the animals! I guess you don't actually have to aim directly at them! There are a few neighborhood cats in my area I'd like to deter from eating the food put out for my cats. I also think the interactive beer pong table is pretty funny. It would have been quite dangerous to have when I was in college!
The variable golf course is quite an interesting system indeed. I can see that some other versions using that same machanism could be the basis for a product that might sell well at some upscale golf courses and country clubs. It could duplicate some of the tougher holes from around the world. There is a whole lot of potential in the concept. And that mechanism is a great idea, good use of fairly standard materials and technology.
