Earlier quoted context omitted.

Are you planning on selling this in the UK? I think you're violating a trademark owned by Channel 4. https://www.ipo.gov.uk/tmcase/Results/4/EU009749805

IANAL, TINLA. AFAIK, trademarks only apply within their market segment so it shouldn't be a problem.

Channel Four have a patent within the computer software subsection of category 9 of the classifications.

The fade between the 3 background vids in the jumbotron of that landing page works really well in Chrome. I've not seen it done like that before, nice work.

And awfully in Firefox, full UI lag.

I know Firefox's implementation makes this its fault, but come on, it doesn't hurt to test the home page in it.

> Faster and better. Got the the site - got a frozen page with the above tagline against gray background for few seconds, then a very choppy video started to play. Couldn't make it past the second pageful, because the page had a massive lag scrolling and it was ultimately unusable. Perhaps have a lighter version with just the content and no bells or whistles?

This put me off too, although only Firefox has responsiveness issues.

Thanks for the heads up. Will get on fixing that.

Looks pretty neat. I'm not interested in iOS per say, but I have a Macbook, iMac and I'm looking at making animation, interactive stuff on those devices.

After looking at your c4's different github repos, it appears you've started some c4 stuff for OS X as well. I'd be interested in this framework if some resources went into the OS X side as well.

Hey all, I'm the creator of C4. Last week we released a new version of C4 (it's entirely Swift). Questions / comments / feedback of any kind would be great, and will only help us make the project stronger.

I've scanned the site and am a bit confused: I guess I was expecting something like Processing[1] or the like, but from the example it looks more like a framework with conveniences, dare I say similar to MPWDrawingContext[2][3] though with a slightly different domain. However, except for a few examples (which look like convenience methods), I don't see anything that tells me what specifically this is for or how my co…

Hey mpweiher, thanks for the feedback. C4 is definitely similar in nature to Processing, animation / interaction / creative coding. I used to be big into Processing, and drew a lot of inspiration from that project as well as OpenFrameworks.

The cosmos tutorial (www.c4ios.com/cosmos) is an end-to-end tutorial for building an app with C4. We are converting a lot of examples from V1 and are currently building new examples / tutorials, all of which will help with understanding what C4 can do and how it can be used.

We are always looking for improved ways to explain C4 and its benefits. We definitely welcome feedback from the community on how to improve our messaging.

As for MPWDrawingContext, it looks like a nice wrapper around CGContextRef. C4 sets itself apart because it handles interactivity (gestures, etc.) and audio / video. You can draw / animate, and build fully interactive interfaces.

C4 is a community-driven open-source project, that has been made through the work of volunteers. We aren't selling the core api in any market. It also has an MIT license so it is free to use for anyone, including in commercial works.

Good digging. We started working on the OSX branch recently. We have a slack channel you can join to ask questions / keep in touch about our progress on that branch.
