Eco may refer to:
Ecology (from Greek: οἶκος, "house", or "environment"; -λογία, "study of") is the scientific analysis and study of interactions among organisms and their environment. It is an interdisciplinary field that includes biology, geography and Earth science. Ecology includes the study of interactions organisms have with each other, other organisms, and with abiotic components of their environment. Topics of interest to ecologists include the diversity, distribution, amount (biomass), and number (population) of particular organisms, as well as cooperation and competition between organisms, both within and among ecosystems. Ecosystems are composed of dynamically interacting parts including organisms, the communities they make up, and the non-living components of their environment. Ecosystem processes, such as primary production, pedogenesis, nutrient cycling, and various niche construction activities, regulate the flux of energy and matter through an environment. These processes are sustained by organisms with specific life history traits, and the variety of organisms is called biodiversity. Biodiversity, which refers to the varieties of species, genes, and ecosystems, enhances certain ecosystem services.
Eco is a wire-frame 3D evolution life simulation game developed by Denton Designs for the Amiga and Atari ST. It was released in 1988 and published by Ocean Software.
The player initially uses mouse or joystick to control an insect, which must avoid predators, find some food, and then find another insect of the same species and mate with it. The player can then unlock one of several "genes", altering the value of which changes their creature. Some changes are only cosmetic and leave the creature in the same species; others can, for instance, make the initial insect a new species with wings and capable of flight. After unlocking multiple genes the player can become a fast dog-like quadruped, a bird, a scorpion or a humanoid. The game does not end until the player starves, is killed by another creature, or deliberately "evolves" into a plant.
InstrumLike a circle in a spiral
Like a wheel within a wheel
Never ending or beginning
On an ever-spinning reel
Like a snowball down a mountain
Or a carnival balloon
Like a carousel thats turning
Running rings around the moon
Like a clock whose hands are sweeping
Past the minutes of its face
And the world is like an apple
Whirling silently in space
Like the circles that you find
In the windmills of your mind
Like a tunnel that you follow
To a tunnel of its own
Down a hollow to a cavern
Where the sun has never shone
Like a door that keeps revolving
In a half-forgotten dream
Or the ripples from a pebble
Someone tosses in a stream
Like a clock whose hands are sweeping
Past the minutes of its face
And the world is like an apple
Whirling silently in space
Like the circles that you find
In the windmills of your mind
Keys that jingle in your pocket
Words that jangle in your head
Why did summer go so quickly?
Was it something that you said?
Lovers walk along a shore
And leave their footprints in the sand
Is the sound of distant drumming
Just the fingers of your hand?
Pictures hanging in a hallway
And the fragment of a song
Half-remembered names and faces
But to whom do they belong?
When you knew that it was over
You were suddenly aware
That the autumn leaves were turning
To the colour of her hair
Like a circle in a spiral
Like a wheel within a wheel
Never ending or beginning
On an ever-spinning reel
As the images unwind
Like the circles that you find
