Talk:Billiard table configuration

Approx how surrounded exactly should an oscillator have to be to count as a billiard table?

A beacon is 50% covered, with two 3-cell "windows" to the outside world and is probably not a billiard table. A lightbulb is probably a billiard table, and can be fitted with up to three one-cell "windows"†. Then some intermediate things in decreasing coveredness…

• The p4 with a cap-like object and a deep 2-cell window
• The similar p8 with a deep 3-cell window
• Test tube baby (less deep 2-cell window)
• Cuphook (2-cell window right next to rotor)
• Great on-off (half as covered as a beacon)
• French kiss, trice tongs (two 3-cell windows)
• Sombreros (two 4-cell windows)
• Overweight emulators (4-cell windows per each corner)
• The "edge-repairing" p6 table

(Some of the all-sides-encased traffic light hasslers (p26, p47, p55, p58…) also resemble "billiard tables" even if in some of these, the "table" is made of smaller-period oscillators.)
