Other Websites!
Here's some other sites I found while browsing the web. If you've managed to skim through everything on THIS page then these might be of interest.
animatronicwheatley.com
A website documenting the process of making an animatronic Wheatley. Includes insights into the project, tips on how to make your own, and a whole gallery of other people's builds! It's all very impressive and a great testament to how creative fans of Portal can be.
Also includes a page relating to a theory on why GlaD0S' character model changes so drastically between Portal 1 and 2, it was an interesting read (and personally I could totally see being the reason).
karenprell.com
If you've looked around the behind the scenes of Portal then this name might've rung a bell. This site is ran by Karen Prell, puppeteer and animator who made all of the animations for Wheatley! This page goes into some brief details on how Wheatley was animated as well as her other projects working with VALVe. If you're curious she listed more of her work on her site including films, puppetry, preformances, etc.
If it weren't for Karen's amazing work we wouldn't have had Wheatley be as expressive and lively as he is now, the contributions she's had to this character cannot be understated enough.
wheatley-science
Fun fact, originally I thought there weren't any Wheatley-centric websites on Neocities. You couldn't even imagine my delight when I found out theres actually are a few out there.
Wheatley-science is a website ran by outer spec, there's a lot of pages to go through including fanfic, video links, and a few other fun things.
Also you don't know how relieved I was to read through the criticism page finally someone who doesn't woobify him. (╮°-°)╮┳━━┳ ( ╯°□°)╯ ┻━━┻
It was a fun site to go through, just be warned you might experience some whiplash going from this sanitized website to wheatley-science's more leisurely language.
