A tiny solar panel, four centimetres wide
Drives seven coloured cogwheels
All arranged inside.
A see-through globe of Perspex
From which a brazen rod
Supports a crystal hexagon
To catch the eye of God.

The machine clings tightly suckered
To a southward windowpane
And when the sky is cloud free
And doesn’t threaten rain
The panel catches sun rays;
The cogwheels slowly move,
Driving round the crystal;
Then rainbows start to rove –

Around the walls and ceiling
Dappling my eyes
Splashing seven colours
With a Rainbow Room Surprise!
