An intuitive, interactive, and immersive food chain simulator. Creatures! is a fun, real-time simulator that allows students to learn the underlying principles of population dynamics. Creatures! recreates a world filled with three types of organisms: grass, rabbits and foxes. Together they interact to create a live ecosystem that plays out in real-time in the form of graphs, bar charts, and a 'field'. Students have full access to many controls where they can manipulate the ecosystem in real-time to watch the dynamics change immediately.

Creatures! Features:
Teach:
1. Food Chains
2. The Spread of Disease
3. Pyramid of Numbers
4. Modeling in applied science
5. Predator/Prey Relationships
6. Effect of man on environment

Applications:
1. Understand food chain dynamics
2. Discover cause and effect for predator/prey relationships
3. Understand and visualize in real-time the effects of disease, asteroids, the influence of man, and more!
4. Provides an introduction to computer modeling

Data Displays:
1. 2D representation of a 'field' showing real-time population dynamics of 3 trophic layers
2. Traditional graph display updated in real-time as simulation runs
3. Dynamic bar chart showing the real-time display of food pyramid

Import/Export:
1. Save or load simulation to disc so specific scenarios can be prepared in advance of class
2. Flexible graphs for Export

Senior Level Concepts:
1. Radioactive Decay
2. Exponential Growth
3. Model a bacterial colony
4. Stochastic dynamics
5. Programmable agent based simulator

Alterable Parameters & Rules:
1. Solar energy input - reinforce importance of photosynthesis in ecosystem
2. Fox death rate
3. Fox hunting ability (predation efficiency)
4. Rabbit birth rate (density dependant)
5. Rabbit disease rate (spread of disease)

For the Teacher:
1. Detailed instructions for introductory experiments
2. Additional tutorials and experimental ideas to assist lesson planning

Other Features:
1. Pre-loaded disasters: fire, asteroid collision, hunting & more
2. Interactive sliders
3. Import field settings for custom designed experiments
4. Simulation engine based on realistic stochastic model
5. Software Requirements
6. Windows XP or above
7. For Mac OS, Windows-based emulator required

Limitations:
* Runs for 2 minutes then must be restarted
