Cap (or covered table) is an induction coil. It can be stabilized to form a period-3 oscillator; see candelabra for a slight variation on this.

Unattended, this evolves into an interchange.

Generation 3 of cap's evolution

Interchange is generation 22 of cap's evolution

Still lifes

There are two ways in which two caps can be arranged to create a still life:

In other rules

In tlife and other rules without S2i, cap is a period 4 oscillator. However, it will still act as an induction coil in the same way it does in standard Life.
