Sometime one morning in 1983 (I think) I was walking through Elsterwick Park on my way to the bus stop to go to school (year 7), when I saw a hot air balloon at low altitude.
On the basket appeared to be a Penrose triangle — the logo for Infinity Limited, the ABC’s science show for kids, which we used to watch at school. Turned out they were filming a scene for an episode — the park is less than a kilometre from the ABC studios in Ripponlea.
To my amusement, the someone’s found it and put it on Youtube.
In each episode, Infinity Limited’s Rick and Krystal would try and solve a science-related problem for their clients, with downstairs company Vortex Ventures, run by Vortex and his assistant Plankton, would try and steal their ideas and customers.
I’m not expecting anybody to watch the whole thing, but the balloon bit is at 16:20. There are also some scenes with Vortex and Plankton trying unsuccessfully to take-off using small balloons — I think that looks like Caulfield Park — the playground at 18:50 looks very familiar, though the big slide has now been removed.
Computer geeks might like to note the presence of an Atari 800 at 1:40. Wouldn’t be surprised if something like it was used to create the first part of the title sequence.
Who else remembers watching this show in the 80s?
