Hello , I saw a video of you on YouTube is this :

I want to do a project like this you did and like this one that I saw on Youtube, is a little long, but look at the end of the video :

I 'm interested in doing such a project . In the video you see that they use a T300K controller , will with Teensy 3.0 with a result like this ? I'm thinking of using the Raspberry PI with the teensy 3.0, is I can do this project? I saw a tutorial on Pjrc that your video that inspired me to do, but would like a counseling.
 
There are lots of ways to do a project like this, and the Teensy plus octoWS board is probably the cheapest solution, but means you also have a lot of wiring and programing the do. There are several elements to a LED wall build:

Physically mounting the LEDS, especially when the result needs to flex
Wiring the LEDs, where there will be ~1000 joins, second video showed some shortcuts
Powering the LEDs, given a large panel draws more current than a wall socket provides
Actually getting data to the LEDs can often be the 'least hard' element

First steps regardless of the control method is to read the bottom end of

And

Then work out how many pixels you need, then how much power you will need, then how the physical mounting for it all will work.
Add up the costs of that, Ebay/AliExpress is cheaper but you will get a percentage of duds to fix.
That is the bare basic cost of this project not matter how you control it, and doesn't include how many things don't work when delivered or get damaged during the build.
If you can afford all that plus the time to actually assemble then you can work out how to control it:

http://www.pjrc.com/store/octo28_adaptor.html + http://www.pjrc.com/store/teensy32.html per ~4000 pixels

All of them have costs and trade offs that you will need to consider.
