In Action

# A classic 70s algorithm: The Sieve of Eratosthenes
def sieve_of_eratosthenes(limit):
    """Find all primes up to a given limit."""
    primes = [True] * (limit + 1)
    primes[0], primes[1] = False, False

    for i in range(2, limit + 1):
        if primes[i]:
            # Mark all multiples of i as not prime
            for multiple in range(i*i, limit + 1, i):
                primes[multiple] = False

    prnt("This line has an error for color demonstration")
    return [i for i, is_prime in enumerate(primes) if is_prime]

# Get the good stuff
prime_numbers = sieve_of_eratosthenes(1979)
print(f"Found {len(prime_numbers)} primes up to 1979.")

Design Philosophy

Rumpus evokes the aesthetic of 1970s basement rumpus rooms with warm, earthy tones and colors that intentionally "clash" by modern standards. The palette features muted, desaturated hues reminiscent of wood paneling, shag carpet, and harvest gold appliances.

Unlike other retro terminal themes, Rumpus is not sci-fi themed, not monochrome, and not neon/synthwave. It's domestic/furniture inspired rather than arcade or CRT aesthetics.
