No ads, etc., just a demo for fun. Will continue to add sequences and improve existing ones through updates, and if I come up with something really cool, will try to make it into a live wallpaper.
The source code will also be made available. It provides a good starting point and tutorial into creating OpenGL apps.
The Gears demo is an open source project intended to help developers learn how to create OpenGL ES programs on Android. The Gears demo was originally written by Brian Paul as part of the Mesa3D project. My implementation includes variations for Java/OpenGL ES 1.x, Java/C/OpenGL ES 1.x and Java/C/OpenGL ES 2.0. I have also added several features not found in the original implementation including touch screen support, VBOs and an on-screen FPS counter.
The FPS (frames-per-second) counter is often used as a benchmark metric for graphics programs. On Android the frame rate is limited by v-sync (typically 60 FPS) which is the fastest rate that a display can refresh the screen. Since Gears is capable of rendering much faster than v-sync on most devices it provides limited benchmarking value.
Note that high-end devices are better served by NenaMark2 as they tend to hit the framerate limit (~60 fps) with NenaMark1.
This application contains various Examples that showcase what developers can do with this engine.
Install this to stay tuned with the progress.

Unlike many other benchmarks, NenaMark measures performance using realistic scenes that could be taken from a typical game and presents the result in frames per second, i.e. providing an intuitive performance number that can be used for realistic comparisons between different devices.
Benchmark results from a wide variety of devices are available on the NenaMark site (http://nena.se/nenamark).
- Skeletal Animation (bones matrix animation), trees.
- Morph Target Animation (blend vertex sets), sun flowers along house wall.
- Bump Mapping (using normal map), stone walls on house.
- Water (reflections, normal animation, fresnel effect), the lake.
- Cloud System (advanced particle system), clouds.
- Cube Map Reflections (w/ dynamic cube map generation), windows on house.
- Smoke (advanced particle system), smoke from chimney.
- Shadow Mapping (dynamic shadow mapping), terrain.
- Texture Channel Animation, sparkling sun.
- Smooth Gradient Animation, sky hemisphere.
- Dynamic lighting (per vertex diffuse lighting), entire scene.
- Lens flare, lens flare from sun at low altitude.

• SINGLE PLAYER: Battle through 20 levels while unlocking new arenas to play in. Score 9 goals to win each match.
• SURVIVAL MODE: For 1 or 2 players, try to keep the disc running until time expires and unlock new arenas while you progress through 8 levels.
• 2 PLAYERS VS: Versus mode. IMPORTANT: In order to play this mode and 2 players survival mode, a smartphone with a working multitouch support is needed. Some smartphones such as HTC Desire and Nexus One suffer from a broken multitouch support, please try the demo first to find out if your smartphone works well.
Every comment about any issue is welcome, thanks and I really hope you to enjoy it so much.
