Hehe
You should have responded: "Almost all existing ones"

I was just sarcastic because of Dingus comment (acting like I was on the dark side).

But yes, we can get paid for some stuff.

I don't think TI hates us ..
They just don't like it.

@Hoffa, TI (TI-Nspire section) does give a damn about us. They have showed it multiple ways:
- By sending email to all magor TI-Communities
- By contacting several community members, allowing them to beta test stuff
- By listening to multiple of our sugestions

@DJ, the print command was changed for something compatibilty with their upcomming SDK. TI did not think anyone would use it (Seriously, I think they never expected sound through it). I pointed them out to some nice stuff you could do with it, and they will change/revert it in the next dev cycle.

Also, the Lua platform is just becomming popular. It's important to know the Lua enviroment was quite hidden to other people than the community until T3 2012.
TI actively showed Lua (with links to the community) to many teachers, who are now started to have fun with it (you can see the trend on the nspire google group).
Also, many Lua programs are being developed 'underground'. I got some projects I haven't posted yet about, and I'm sure others too.

Now, I don't think the TI community is dying. I think it's in a special fase, as there are many factors we did not have previously.
I have to agree with Adriweb in many points too, and I don't think we have to choose a side. TI knows that many TI-Planet admins such as Adriweb work on Ndless, yet they continue to have contact with them. TI clearly isn't forcing us into choosing a side. And if the community forces us to choose .. well then I know what side I would be on.
But this isn't the case, and I'm happy to be able to work both with TI and the Ndless dev team

I just wanted to clarify some Nspire stuff

- There is no on-calc editor in 3.2. The student software comes with a SDK built in. However, there are multiple Lua programs that allow you to code on-calc, so this isn't a problem.
- TI cannot fully lock the Nspire, there will always be holes to exploit. It might take longer, but as Olivier stated he will not give up on Ndless development. And I will not either.
- TI is actively improving the Lua language, and they are very open to suggestions.
- TI isn't that evil either. I recently asked them why they removed/disabled the print command in Lua. They reason was not to annoy us, and now there is a very big chance that it will return in the OS after 3.2.

And as Albert stated, great stuff in the Nspire scene are just beginning.

Looks nice

What about some way to add buttons/inputs to the screen and make the arduino respond to it?

I have only briefly looked at the non-English TI community, but I think they are an important part of the TI community history and should be involved in this project as well.

I've been updating the TI-Planet page, and think the other TI-Planet admins will contribute too

Does anyone here have a good algorithm to split a concave polygon in multiple convex ones?
I've looked a bit, but can't find an easy solution. In the worst case I just could use triangulation, but that's overkill in my opinion

TIA
