In keeping with the exhibitionist-diary concept that is called “blog,” I’ll write something today even though I have nothing going on worth writing about. I am working on a switch for the large RBS (Rolling Ball Sculpture) and it’s giving me trouble. It’s not the kind of trouble…
Continue readingRolling Ball Sculpture I’ll need to post some photos soon. I’m working on a billiard ball rolling ball sculpture. It is about 4.5 feet tall and has a chain lift like a roller coaster. The cool feature of this sculpture is the authentic roller coaster look and feel….

I have some simply JavaScript code that runs when a button the page it clicked. <input class=”optionsbutton” type=”button” name=”ButtonHide” value=”Show” OnClick=”showoptions( true )”/> The showoptions function is quite simple as are the functions it…
