Progress not always for the better…

I have “ported” my rotozoomer from the Nokia 770 to the FreeRunner/Neo

For a video output speed comparison I have made a video of it running on a Nokia 770, a Neo and a FreeRunner side by side.

Rotozoomer Demo

Rotozoomer Demo on YouTube

The result is somewhat sad, but judge for your self.
Just remember that the 770 has 1.25 times the pixel count of the Neo and it is a lot older too.

Sources are obtainable from the Maemo Garage page.



  1. Btw. the zoomer is running with a 256×256 texture.
    The Nokia version can select from 1024×1024, 512×512, 256×256 and 128×128 textures

  2. Yeah, I have a freerunner. Got in on a group purchase when they were first launched. It’s been a big disappointment for me. Haven’t touched it in months…

  3. How FreeRunner can be slower than Neo1973? It has a lot faster processor? Has it something to do with Glamo or what?

    • Yes it is caused by the GFX chip sitting on the external address/data bus.
      The internal silicon bus is a lot faster.. (As far as I know)

      This was the downfall of the Nokia 800 as well…
