I am very happy to finally release my new product: a Live Wallpaper for Android.

One of my hobbies is enjoying this unique Android feature: a wallpaper that moves and changes over time. Whenever i activate my tablet, i watch for a short moment, meditating over the shapes and colors. When i use my smartphone, the Live Wallpaper makes me smile.

So i decided to make my own. I had this old idea for an Adventure Game Engine titled PaintVenture, where not only playing the game but watching the Pictures was core of the game. Looking back, it just waited for me to create a Live Wallpaper from it.

I prepare images and configurations for my tool chain, then the adventure engine uses brush strokes to mimick images. The result is a drawing process from which the painting emerges as if a painter would do it manually, just much more quicker. Just as if one would watch an Open Canvas recording.

Playing back this drawing process on the Android feels unique to me. Sitting in front of my PC screen is nice, but having it somewhere comfy, allows me to change the settings and play it back really slow. Meditating over an hour until the drawing finally appears - or watching it together with my girlfriend, appearing in less than a minute, puzzling which of the images it is. 'The duck', 'No', 'The castle ... maybe' , 'I think it must be!',

Take a look at the short trailer, but better just try out the Live Wallpaper from Android Market for free.

If you like what you see, you can support my work by using in app purchases with more paintings in different topics. In the future I'd like to extend the available sets of paintings with even more topics. Stay tuned :)

PS: i thought about the idea that people might be interested in having their own images used as Artisan paintings. Interested? Shoot me an email!

I invested over 200 hours to create the new website for the triniyoga studio. Thanks to Julia Zaadstra for the visual design, i was able to focus on the technical details.

a short sample of my realtime cloud simulation. i'm running it using an old version of irrlicht 3d engine but the cloud system is 3d engine independent. the simulation creates size independent cloud systems (think of boxes) in which clouds can move, a game world can then have multiple systems that are only rendered when their bounding box is visible. the rendering is done via the 3d engines main thread, while the cloud simulation of the multiple systems is done in one simulation thread that manages the simulation of all cloud systems.

on my core i7 870 + gtx 470 (bought 2010) these are the stats:
-simulating one (medium sized) cloud system for one iteration step: ~15ms
-updating the render data: less than 1ms
-rendering in 1280x720 (camera outside of clouds): 1500+ fps
-rendering in 1280x720 (cemera inside of clouds, lots of overdraw): 800fps

i wrote this tech demo in one week (60+ hours) to celebrate the start of my 9 1/2 weeks game development only time (yay, away from my dayjob!).

after another year has passed i continued to work on my "squareworld" prototype (from 2008). i have a new gameplay idea and am currently implementing whats necessary for that. this alpha preview video shows a nearly unlimited world dynamically generated as you run across it. gameplay: collect the (orange) ghosts one after another trying to reach the next one before your time (top left) runs out. pickups: money = silver/gold/crystal, bonus time = green, loose time = red (hint: audio is only mono in this video, as adobe premiere was having trouble properly rendering stereo (right channel was completely mute) and i and adobe support still have trouble figuring out why)
