** 2007, Frances Gruber Safford, American Furniture in the Metropolitan Museum of Art:The left drawer runner is probably replaced. Nail holes on the upper surface of the stretchers suggest the piece once had a bottom shelf. Modern metal gliders have been added under the feet.
* A kind of garden swing.
** 1978, Tom Reamy, Blind Voices, published 2003, page 73:Francine sat in the glider on the porch, swinging lightly, her mind a thousand miles away. The chain squeaked a little, almost like a cricket.
** 2011, Mary Biever, He Uses It For Good!, page 5:Then I went into the backyard, which had a flower-covered arbor, a small garden wall, and room behind it for a garden. Swings and gliders adorned the yard.
* (cellular automata) In the Game of Life, a particular configuration of five cells that recurs periodically at fixed offsets and appears to "walk" across the grid.
    Hypernym: spaceship
** 1989 December 22, Norbert Roestel, “CA-LETTER”, in comp.theory.cell-automata‎ (Usenet):By the way, what happens to a beehive which is under attack by one or two gliders such as pictured:
** 2006 September 28, Dave Greene, “Small Heisenburp device in Conway's Life”, in comp.theory.cell-automata‎ (Usenet):I believe it is indeed new -- I've gone back through everything I can find, as far back as the early 90's when Heisenburp devices were first invented, and there don't seem to be any reactions based on a glider suppressing a blinker.
** 2008, Derek Abbott, Paul C. W. Davies, Arun Kumar Pati, Quantum Aspects Of Life, page 246:In Conway's Life interesting effects can be obtained by colliding gliders.
** (by extension) Any spaceship in a cellular automaton, especially one which exhibits glide reflection.
*** 1989 June 11, David Hiebeler, comp.theory.cell-automata (Usenet):It is a reversible rule, and an interesting one. Shortly after I implemented it, Chris and I were watching it run from a small random configuration of vants, when we noticed a structure consisting of 2 vants propagating away from the others -- it is a glider of sorts, consisting of 2 cooperating vants moving along, erasing each others' trail.
*** 2003 May 13, Frank Buss, “Totalistic Explorer and squirm”, in comp.theory.cell-automata (Usenet):I wanted to test some totalistic automaton and the glider with the B024S1 rule, which Ilmari Karonen described.
*** 2007 May 12, Dave Greene, “Wanted: 2D CA, "as complex" but "denser" than Life”, in comp.theory.cell-automata‎ (Usenet):By contrast, consider a rule like Seeds (B2/S) that has "gliders" and oscillators and so forth, so theoretically it might support universal computation somehow.
* A vehicle, of a usually motorised type, without a powertrain.
* (entomology) Any of various species of dragonfly that glide on out-held wings while flying, such as the common glider, Tramea loewii, of Australia, New Guinea, Indonesia, and the Pacific.
