Halloween 2010: Jaws

Meet Bruce the Shark:

This year we decided to decorate to the theme of the 1975 film Jaws. Bruce is our replica of the shark built for the film. The makers of the film named their shark Bruce and we kept the name, at first because we wanted our shark to be as menacing and lifelike as in the movie. Later our shark proved to be as unreliable as the movie prop; thus, piling on to the naming convention.

Our Bruce is made of fleece – known to be the most menacing of fabrics – and has an internal pneumatic movement system that would scare most industrial engineers. Of course, we’ve already pointed out that Bruce didn’t work, so most of his guts were removed and replaced with Winnie-the-Pooh-like stuffing.

Mechanical problems hampered the filming of the movie Jaws and forced the filmmakers to go in a different direction that may have improved the film. Likewise, our Bruce’s inability to swim caused us to change course and concentrate on the periphery of the set. The “set” in this case being our front yard.

The focus became a talking skeleton that we first used in 2006. This year we upgraded it to playback a different spiel each time someone approached him. And so he was re-christened “Quint”, the character played by Robert Shaw in the movie. We ripped the entire DVD and broke out all of Quint’s monologues.

To fill out the environment, we added some octopi, helium filled jellyfish, and projections of various other sea life. There was some discussion about how far we could blur the line between reality and artistic license. For example, does it make sense to have fish swimming on the house? We projected a rippling water effect on to the sidewalk further twisting the physical nature of the environment, but it didn’t matter. Little kids look past the laws of physics. Must be video games or something.

In the end we were really happy with the result. With 230 kids at the door it was really worth the effort. We were even happier when a trick-or-treat’er commented that he liked the theme and, more importantly, that he noticed that we have a different theme every year. That was really gratifying. Of course, he suggested that next years’ theme be torture related.

Halloween 2009: Gigantic Floating Eyeballs

We gave out candy to 196 kids plus one father in a Rush concert shirt. A good night by anyone’s standard. And technologically, it was a thing of beauty.

I have to say that the start of the evening was looking grim. The wind had picked up. The whole rig was in danger of becoming a sail. My neighbor was still mocking me about the fantastic set of hooters I had constructed above the doorway. Then the sun went over the horizon and all was good.

The video screens lit up and the sound was turned on. It all just… worked. As if I had just gone out and bought the system at some yuppie Halloween superstore (something I was accused of several times).

The key thing here is, in fact, the sound. Yes the eyeballs have sound. No it doesn’t make any sense, but it’s just one of those things I’ve learned that everything must have a sound to have an identity. So I gave it a voice and you can hear it in the video below. The other thing I have learned is that there is no substitute for proper amplification. This year I employed the Roland KC-350 combo amp which made the house shake. It could be heard a block away. It made dogs howl.

Anyway, kids were truly mesmerized. I’m used to the parents wanting to take a second look, but children actually delayed their pursuit of sugar to stand and stare. There is no higher complement.

Thanks to all who dropped by. For those who couldn’t, this please enjoy the video. And don’t forget to turn the sound up.

Gigantic Floating Eyeballs, Part 4

Ruth was the first to suggest that the video screens looked like breasts. I didn’t see it, which is shocking, but I was focused on the end result and always had seen the screens with the image of an eye even when the projector is off. Now it is obvious: round and firm, yet supple with perfectly centered…

Enough of that. But the first thing my neighbor said when he saw them was “Going pornographic this year?” Now the pressure is really on. Even if I can get this thing to work, there is a chance that I will mistakenly crossover from scary to erotic.

One more thing to do: design and build the motion control system. I left this to the last minute since I work with software every day. The plan was to create a pseudo-random set of movements for the two pneumatic cylinders. Now I am out of time.

I was going to scrap the whole motion thing, but then it struck me that I don’t need software at all. Each input to the cylinders has their own speed control. If I just add a simple on/off timer, the cylinders can be set to move in and out at slightly different speeds, thus creating three dimensional motion. It looks like this:

I know… messy. But try to remember we are in panic mode. Time to put this thing up on the roof.
