Infinity Limited was an Australian educational television program focused on science, produced by the ABC in Melbourne from 1982 through 1984. Although its duration was short, the series became well-liked among primary school students across Australia. The show comprised 37 episodes, each aired between 12 and 19 times during the period from 1982 to 1991, with the exception of episode 83/9 titled "The Big Heater," which was broadcast only three times.

The cast featured Kim Trengove and Stefan Dennis portraying Kris (Kristal) and Rick, partners running a small enterprise named Infinity Ltd. After Stefan Dennis left following the twentieth episode in late 1983, Mark Little joined as Rosco for the remaining seventeen episodes. Infinity Ltd. focused on addressing straightforward science-related challenges presented by clients. Their office was situated above Vortex Ventures, a competing firm that frequently attempted to lure away Infinity Ltd’s customers but rarely succeeded. Ross Williams played Valerian J. Vortex, the inept proprietor of Vortex Ventures, while Ian Scott portrayed Arthur Plankton, his long-suffering assistant who often demonstrated more intelligence than Vortex acknowledged. Plankton regularly undertook unpleasant duties such as spying on Infinity Ltd. The rivalry between the two companies was depicted as a minor business nuisance rather than a serious threat.

Kris

Kristal (Kim Trengove), commonly called Kris, represents one half of the Infinity Limited partnership. Although their collaboration is relatively equal, Kris frequently holds final decision-making authority and tends to assign physical tasks to Rick. She suspects Rick may take it easy during breaks but maintains a close friendship with him; while a romantic connection is hinted at, it is never explicitly shown due to the program’s young audience. Kris appears to be in her early twenties.

Rick

Rick (Stefan Dennis) exhibits a more doubtful nature and often needs convincing before accepting new concepts. He is diligent in his work but values downtime, leading Kris to believe he occasionally avoids responsibilities. Rick exits the series for reasons not explained and is succeeded by Rosco. His age also seems to be in the early twenties range.

Rosco

Rosco (Mark Little) takes over from Rick as Kris’s partner at Infinity Limited. Known for his practical skills and ability to construct things, he provides hands-on expertise while Kris concentrates on scientific theory. Rosco appears to be in his early twenties.

Vortex

Valerian J. Vortex is the owner of Vortex Ventures, the competitor to Infinity Limited. Characterized as greedy, lazy, and unscrupulous yet not entirely lacking intelligence, he grasps scientific ideas at a superficial level but lacks patience for deeper understanding. Vortex creates various inventions that initially succeed but ultimately fail due to significant defects. Claiming genius status, he frequently disregards his assistant Plankton’s usually sound advice. His plans typically involve get-rich-quick schemes marked by poor preparation despite imaginative designs. Vortex almost always wears a blue suit and tie, sports a moustache, and has a distinctive horn-shaped hairstyle reminiscent of the Pointy-haired Boss from Dilbert. He seems to be in his early to late thirties.

Plankton

Arthur Plankton serves as the beleaguered assistant to Vortex and is seldom called by his given name. Whereas Vortex exhibits intellectual indolence, Plankton is more prone to physical lethargy, likely reflecting his unwilling participation in Vortex’s experimental endeavors. In contrast to Vortex, Plankton generally strives to act ethically but frequently finds himself misdirected. He possesses slightly greater intelligence than Vortex and often detects flaws in Vortex’s schemes, though his insights are typically disregarded. His usual attire consists of blue denim trousers paired with a grey V-neck sweater adorned with yellow and maroon stripes. His age appears to be in the late twenties or early thirties.

Relationships

There are indications that Kris and Rick share a romantic relationship, with their office space seemingly doubling as their home. In the episode "The Generation Gap," Kris’s mother is anticipated for dinner, suggesting the office is located within their residence. Additionally, in "Melting Moments," Kris’s tender gesture toward Rick reinforces this notion. Miss Abernathy displays an interest in Vortex until his inventions fail repeatedly. Plankton shows attraction toward a librarian, but his advances are interrupted by Vortex.

Episode Structure

Episodes generally revolve around Infinity Limited being contracted by clients encountering novel challenges. The team investigates various potential solutions and performs experiments to determine the most effective approach. Approximately half of the episodes feature Vortex dispatching Plankton to spy on Infinity Limited through an air duct connecting their offices; Plankton then attempts sabotage and pitches alternative ideas. Other episodes depict Vortex engaging in unrelated schemes that inadvertently intersect with Infinity Limited’s problems. Consistently, Vortex’s plans collapse due to his own errors.

The lack of knowledge demonstrated by Vortex and Plankton functions as a narrative tool to explore and clarify scientific principles through their inquiries and discussions, thereby educating viewers. Similarly, characters from Infinity Limited elucidate concepts among themselves or consult specialists who provide explanations accessible to all characters. These educational moments are seamlessly woven into the storyline and visually demonstrated to maintain engagement.

The series highlights the importance of critical thinking by contrasting comprehensive investigation against premature conclusions while addressing environmental and scientific issues pertinent to innovation and problem resolution in business contexts.
