There are problems with all of these. The hymn is a little short (maybe a doxology) and has no lyrics plus the bass line needs work and a better synthesizer / real instrument. The middle third of the improvisation should be replaced with something harmonicaly different ( less repetetive), which can be done when it’s not 2 at night.
Two forklifts are used in the warehouse at my job, a Yamaha propane 2-stroke and a Wiggins electric. The Yamaha has a top speed of 20 mph and the Wiggins can manage 15. Both have telescopic forks capable of lifting 500 lbs over 15′ in the air. These things zip up and down the isles, often backwards, and the drivers are used to people moving, so you have to be aware enough to step out of the way. I was nearly flattened by the Yamaha last week while looking down at my notebook; as it whipped past my nose I noticed a humorous saftey sign on the engine cowling depicting a man standing on the fork, being lifted into the air.
While eating lunch I was reminded of the safety sign by the shape of my tuna sandwich and began to think on it. Safety signs warn against dangerous activities. Often the danger is obvious but people choose to ignore it because the activity is fun or useful, hence the need for a sign. Saftey signs can therefore provide good ideas for fun or useful activities.
Being lifted 15′ in the air is fun and useful by itself, but combine it with the speed of the forklift and some assorted warehouse junk and you get a spectacular fusion of feudalism and technology: Forklift Jousting!

Forklift Jousting requires teams of two: a driver and a lancer. First, each driver picks up a pallet to serve as a platform for the lancer. The lancer is armed with his choice of weaponry. I would personally use either a machine axle or a 12′ cardboard shipping tube, along with the lid from a sunblock drum as a shield.
When the contestants are ready, the forklifts retire to opposite ends of the warehouse. At a pre-arranged signal, the drivers accelerate and pass as close and as quickly as possible while the lancers try to knock each-other to the ground. Rules are as follows:
1) The forklifts must drive backwards, otherwise a jouster could land in front of his machine and be run over.
2) If the forklifts collide, the round is a draw.
3) The driver may raise or lower the fork as he sees fit, but the jouster must remain above the roof of the forklift so he is not shielded by the body of the machine, at pains of a 2 point penalty.
4) 1 point is awarded for disarming an opponent, two points for knocking him off his pallet. A bonus point is awarded for disabling the opposing driver or forklift without crashing into it.
5) If a jouster topples his opponent, he may choose to dismount and resume combat on foot, in which case additional points are awarded as follows: 1 point for disarming, 2 for bringing an opponent to the ground (both knees touching the floor), 3 for a successful beheading. If a contestant brings his enemy to such a pass that beheading is inevitable but chooses to show mercy, the judges may award beheading points anyway.
6) At the end of the tournament the team operating the Wiggins is awarded an extra point as compensation for it’s lower speed.
The winner is decided after three passes by a panel of judges and is awarded the looser’s next paycheck.
The summer weather in California is very frustrating. I want to lie there all day, and when I do go out I’m reduced to somnolescence and unable to hold up a conversation. By the time it gets cooler and I start to wake up it’s 10:00 at night and time for bed.
