Here are some patterns, mostly ones that I built, in RLE format:

**Oscillators**- Stamp Collection (Collection of 650 oscillators known by 1995)

- New billiard tables (Billiard tables found from 1997 to 1998)

- New billiard tables (2008) (Billiard tables found in 2008)

- New billiard tables (2009) (Billiard tables found in 2009)

- Signal injectors (Collection of 2c/3 and 5c/9 diagonal signal injectors)

- Crystal and decay oscillators

- Back and forth fuse (p1200 oscillator with a pi heptomino moving through a line of blinkers)

**Glider guns**- Period 30N guns (Based on 2 p30 streams colliding)

- Wobble gun & pseudo kickback (Gliders modify p30 guns)

- Period 44 and 50 guns

- Period 132 gun

- Cyclotron (Period 874 gun based on 3-glider collision)

- 3 Herschel-based guns (Gliders create Herschels, which emit gliders)

**Puffers**- Period 8 puffers

- Period 20 puffers

- Period 24 puffers

- Period 36 puffers

- Corderman spaceships and puffers

**Sawtooth patterns**

- Tractor beam sawtooth patterns (Diagonal with e.f. 6 and orthogonal with e.f.s 6, 11, and 21)

- Sawtooths based on bouncing spaceships (Diagonal with e.f. 4 and orthogonal with e.f. 25)

- Sawtooth with external timing (e.f. = 2; by David Bell)

- Parabolic sawtooth (This one is not exponential.)

- Hacksaw (Sawtooth with e.f. 9 based on p8 blinker puffer)

**Breeders**- Two p60 breeders

- Unusual Corderman-based breeder

- Pufferless breeder

**Unusual growth rates**- Three patterns with (apparently) irrational linear growth

- Life computes pi (Population is ~ (pi-2)/720 t^2)

- Sqrt gun 10.1 (Population is ~ C sqrt(t))

- Sqrt gun 3.0 (Population is ~ C sqrt(t))

- t^1.5 (Population is ~ C t^(3/2))

- Caber tosser (Population is ~ C log(t))

- log(t)^2 (Population is ~ C log(t)^2)

- t log(t) (Population is ~ C t log(t))

- t log(t) by stifled breeder (Population is ~ C t log(t))

- t log(t)^2 (Population is ~ C t log(t)^2)

- Irrational density pattern (Population is ~ C t^2, with C = (3-sqrt(5))/4320)

- t^(1/3) pattern (Population is ~ C t^(1/3), with C = (75/16)^(1/3)

**Glider syntheses**- 2, 3, and 4-glider syntheses

- Still-life syntheses by David Buckingham

- Still-life syntheses by Dean Hickerson

- Billiard table syntheses by David Buckingham

**Miscellaneous**- Ruler pattern: produces the sequence: 1 2 1 3 1 2 1 4 1 2 1 3 1 2 1 5 ...

- Jagged lines: jagged lines of gliders crash to form a jagged line of block pairs

- 4 breeders produce cloud-like regions made of gliders

- Collection of glider eaters

- Methuselahs

- Reburners (Output of puffers is reburned at a slower speed)

- Exponential and linear aperiodic patterns

- Block pusher 5 (Bounded population, aperiodic pattern. Closely related to sqrtgun 10.1)

- Primer 4 patterns which compute prime numbers, 1 by me and 3 faster ones by Jason Summers

- Pi heptomino conduit Pi heptominoes move at 3c/10 between pentadecathlons

- p30 stream crossing

- p30 PRNG (Pseudo-random glider generator)

- Spiral decay pattern

- Downstream crystal

- Patterns formed from the digits of numbers

- Alan Hensel's decimal counter

**Other rules**- Slow alien spaceships (and a breeder)

- Spiral and polygonal growth in B34568/S15678
