For a while, Vogtinator has been working on a new Ndless 3D engine for the TI-Nspire, but from it, spawned a brand new Minecraft clone: Crafti. In the past, Chockosta released nCraft, a 3D Minecraft clone for that calculator, but the use of floating points prevented him from using advanced and textured graphics. Over a year later, Vogtinator managed to push 3D even further, as you will see in this quote from him:

It's time for the newest, greatest, most stable and best release yet: v1.0!
Bad news first: No major no features, no redstone yet. But I'm working on it 
I wanted this release to be stable and with all known bugs fixed, and redstone is the opposite...
I also focused on performance. Just try it out yourself, it's a big improvement!

But now the good news:
New features:

• Support for non-cx cals! Due to the limited amout of RAM the worlds can't get very big
• Font rendering! 
  
• Help screen! 
  
• Settings!
  
  Also reintroduced transparent leaves. You can change the walking speed now!
• Some reworked graphics!
  
• Fast mode! 
  
  The "face-combining" can be seen here, so 4 faces are drawn as two triangles now.

Bugs fixed:

• Fluids not updating unnecessarily
• Wrap around in block list
• Use the touchpad/clickpad for navigation!
• X and Z-Interpolation issues fixed!
  
  You can see close blocks now, have fun digging!
• Some refactoring..

That's about it. It took much longer than expected, but I tried to fix every bug I found 
And a short note at the end: I changed the savefile version again, so if your world doesn't open, you'll have to open and save it with v0.9 first.

Remember that to use this game, you need Ndless. Do NOT upgrade to OS 3.9, else you will never be able to use any Ndless program again!

Anyways, that is looking awesome indeed

That's called being awesome.

I tried the game by the way and it's really impressive. It has come a long way from the previous version.

I'm not naive enough to believe that it's not a random guy calling himself Notch on ticalc.

Yeah it's very common for fans of a big name to use their name on forums or even people trying to pass themselves as that person to get attention.

Even if the official author didn't do a Minecraft clone for calcs I wouldn't be surprised if he sent C&D to all calc Minecraft authors one day since he seems to like those


However it's not to make money or anything like that that people do Minecraft games for calcs. In the case of the Nspire clones it was mainly to show it can be done.
