Interactive 3D simulation of the 1949 MONIAC water computer

Gemini 4 Argon High/ Antigravity.

I am building a new Three.JS skill for Gemini 4 Argon, and the results are really promising; hopefully I can publish it soon.

Build an interactive 3D web simulation (index.html) of the 1949 MONIAC Water Powered Economic Computer using Three.js, plus a 3-minute 1080p demo video showing a human mouse operating the machine with gentle background music.

What This Machine Is:
In 1949, before digital computers had screens, economist Bill Phillips built a 2-meter-tall machine at the London School of Economics that simulated an entire country's economy using 100 litres of coloured water flowing through clear plastic tanks and brass valves.

1. The 3D Machine and Colored Water Tanks
Build the cream- steel frame holding three clear tanks with millimetre rulers (in Millions of Pounds and Liters), connected by clear pipes, moving water streams, brass floats, pulleys, counterweights, a spinning bottom water pump, and a spinning paper chart drum at the top right:

- Top Red Tank (Government Treasury): Tax money flows in at the top, and government spending pours out the bottom.
- Middle Blue Tank (Household Spending): The money families have left after taxes to spend in domestic shops.

- Bottom Green Tank (Bank Savings and Business Investment): Money saved in banks waiting to be loaned out to businesses.

2. Interactive Controls That Visibly Move the Water Levels
On the left panel, create 4 sliders and 4 historical preset buttons that physically turn the 3D brass valves and make the colored water levels rise and fall across the tanks (from 15% to 88% full) within 1 to 2 seconds while keeping all 100 litres of water balanced:

- Income Tax Slider (5% to 50%): Raising taxes opens the top brass tax valve, filling the Red Treasury Tank high into a surplus while draining the Blue Household Tank. Cutting taxes drains the Red Tank and refills household spending.

- Government Spending Slider (0 to 2,500M Pounds): Dragging spending up opens the treasury valve, draining the Red Tank and pumping water into the Blue Household Tank, lifting its brass float and spinning the bottom pump faster.

- Bank Interest Rate Slider (1% to 10%): Raising interest rates closes the investment valve, backing water up inside the Green Savings Tank. Cutting interest rates releases stored savings back into active business investment.

- Foreign Imports Slider (5% to 40%): Raising imports opens the bottom drain valve, leaking spending out of the Blue Household Tank into foreign trade.

- 4 Historical Preset Buttons: 1947 Austerity, 1949 Sterling Crisis, 1950 Export Boom, and Reset Equilibrium (2,400M Pounds GDP).

- Live Paper Chart Drum and Telemetry Card: As the water levels rise and fall, the floating weights pull thin cables that move a red ink pen across the spinning paper drum at the top right, drawing a live graph of National Income (GDP).

- Click Any 3D Part to Inspect It: Clicking any 3D tank, brass valve, or the paper chart drum highlights that 3D part in a bright gold wireframe and shows its live litres and flow rate on the right readout panel.

3. Four View Modes (Top Bar Tabs)

- 01 Operating Console: Full view of the machine so you can drag sliders on the left and watch all three colored water tanks rise and fall together.

- 02 Valve and Tank Close-Up: Closer view of the brass valves, pouring water jets, and floating weights while keeping the neighbouring water tanks in sight.

- 03 Exploded Plumbing View: Slides the front tanks, middle valves and pipes, and back steel frame apart along four steel guide rails with clean labels pointing to each layer.

- 04 Live 2D Blueprint: Flat engineering diagram overlaying live moving flow arrows and Liters/min equations directly over the tanks and pipes.
