* The mecha type names (LFO and [[Music/TheKLF KLF]]), as well as many other things, are musical references.
** There are many references to acid house - "Pacific State", for instance, refers to [[http://youtu.be/6jQ_bOP0HfY this number]] from 808 State.
** Most of the episode titles are named after songs, primarily from AlternativeRock and electronic artists. Examples include "[[Music/NewOrder Blue Monday]]", "[[Music/PrimalScream Higher than the Sun]]", "[[Music/BeastieBoys Ill Communication]]" and "[[{{Music/Oasis}} Morning Glory]]".
* There are many shout outs to surfer culture.
* Two characters, Woz and Jobs, are named after Steve Jobs and Steve Wozniak, the creators of Apple.
** Jobs even looks the part, having the sufficiently similar appearance to real Steve Jobs. Woz... well, if you squint really hard and discount his fashion sense.
* Gidget and Moondoggie are named after characters from the ''Gidget'' book/TV/film series who have the same relationship. Mondoggie's real name, as stated on his pilot license, is James Darren Emerson -- a composite reference to the actor playing the original Mondoggie role, James Darren, and Darren Emerson, a noted electronic musician.
* Episode 20 features a prison called "Dabu Ghraib".
* Shout outs to classic giant robot shows out the wazoo.
** The three annoying kids are designed after the three annoying kids from the original ''Anime/MobileSuitGundam''.
** Weird pink explosions are from ''Anime/MobileSuitGundam''.
** The Nirvash typeZERO is nicknamed the "[[Anime/MobileSuitGundam White Devil]]."
** Ray & Charles' mechs are painted in Max & Miriya's colors from ''SuperDimensionFortressMacross'' and have strong similarities to ''Gundam'''s Ramba & Hamon. There are [[{{Homage}} similar interactions and showdowns]] between the Gekkostate and the Beams and those sets of characters.
** Their names are references to both ''RayCharles'', the Jazz musician, and keeping with the series' less prevalent architecture motifs, Ray and Charles EAMES were a married pair of famous modernist architects.
** Anemone is a violently insane genetically altered TykeBomb in a red & black version of the hero's mech, similar to the situation with ''[[Anime/MobileSuitZetaGundam Zeta Gundam]]'''s aptly named Psyco Gundams.
** Several elements of the plot & characters resemble elements from ''[[Anime/AfterWarGundamX Gundam X]]'', though this may be coincidence.
** In TheMovie, there's a spaceship called the [[{{Macross}} Megaroad]]
** An event in the plot happens at co-ordinates [[Anime/MobileSuitGundam0080WarInThePocket 0080]] [[{{Gundam0083}} 0083]].
** The Nirvash's [[spoiler:Spec3]] form is basically the Eureka Seven form of the Gunbuster, pilot seat and all.
** Every single episode of the series shares the name of a real life song.
** Renton, Eureka and Anemone could be easily seen as [[{{Expy}} Expies]] of [[Anime/NeonGenesisEvangelion Shinji, Rei and Asuka]], both visually and in terms of personality. Beyond this, the second episode of the series [[WholePlotReference very clearly draws parallels]] with [[Anime/NeonGenesisEvangelion Eva's]] second episode, as examined by a blogger [[http://ghostlightning.wordpress.com/2009/05/07/22s/ here]].
-->The key comparison is how the lead characters, notably Renton Thurston and Ikari Shinji (boys, both 14 years old) in the first episodes both end in a cliffhanger where the leads are in mortal danger: Evangelionís end while Shinji is in the thick of the battle while Eureka SeveNís end with Renton joining the fray.
* Renton's LFO toy is similar to Popy's and Bandai's late 1970s and early 1980s Chogokin ("SuperAlloy") diecast toys, including blocky OffModel design and RocketPunch spring-loaded fists.
* Greg Egan, aka Doctor Bear, is a reference to two science fiction authors, Creator/GregEgan and Creator/GregBear.
* Renton is named after Mark Renton, from the movie Literature/{{Trainspotting}}. Similarly Diane Thurston, Renton's sister, is named after the character Dianne Coulston of the same film.
* Warsaw is also known as "The Joy Division". Warsaw is the name the band Joy Division previously went by.
* For TheMovie, PeterPan is mentioned at least 3 times and Renton and Eureka are even called "Peter and Wendy".
* Gekko-go's gunner and owner, Ken-Goh, is a reference to Kengo Watanabe, an old buddy of the series chief scriptwriter, Dai Sato, with whom he also manages an indie electronic label Frogman Records.
* Various HumongousMecha designations in the series are mostly taken from the synthesizers' (mostly Roland) model numbers. The Devilfish is a famous mod for the Roland TB-303 that vastly expands the tonal capabilities of the synthesizer
* Whenever members of the Gekko use codenames, they use characters and such from Literature/AliceInWonderland.
* Frank Lloyd Wright's Falling Water seems to have found an odd home in the depths of a mine.
** A character named Lloydwright appears a few episodes later as a contact of Charles and Ray.
* Renton's father Adroc Thurston seems to have been named for Adam "Ad-Rock" Horowitz of the Beastie Boys, and in one episode he's said to have worked with Drs. Yauch and Diamond (Adam "MCA" Yauch and Michael "Mike D" Diamond).
* The Second Summer of Love is an event in the series that could potentially destroy all life. It's named after a time in '88 when European music attitude and composition was fused with the budding American techno and electronic, opening up new music and ideas for the 90's and beyond.
* The [[TheBeautifulGame Soccer]] game in episode 39 is a big shout-out to Anime/CaptainTsubasa.
** Moondoggie calls his shots, both of which have different names but are exactly the same.
** Most jumps last at least three minutes. Three minutes that the jumper will spend in some geosynchronous orbit five meters above the field.
** Eureka and Renton's using Holland to jump (I'll let you work the physics of that), meet in mid-air and performe a Twin Shoot.
** Complete and utter disregard of physics.
