   Hi all,

   Fresh as a very fresh thing and brand-spanking new on the app store I give you 'Bauble'. Bauble essentially simulates a Christmas tree ornament bobbing and swaying about on-screen using the accelerometers and Chipmunk physics engine to looks realistic. Tapping the screen lets you choose from a variety of different backgrounds and baubles.

   We started off thinking we'd make this a really simple, mostly static image app but the integration of physics and a load of, really gorgeous, Victorian art and illustration has left it much cooler looking than we ever intended at the start. Hope you enjoy the video:

   Bauble is the 2nd app we've released, and (having spent a lot of time with core animation) I have to say THANK YOU to Riq, Cocos2d genuinely has helped develop cooler looking apps in shorter time-frames. Bauble took us (two people) about a week of hard work to go from concept to finished app. Thanks in advance for any feedback/reviews, happy holidays!

   thanks ... honestly we're really pleased with how polished it's ended up - slightly surprised ourselves even ;)

   Yeah - I love the look of the rotating menus, and the overall feel. Nice job!

   cheers ... you wouldn't believe how *fiddly* it was to get the bauble picker wheel at the bottom using chipmunk physics, touch/swipe movements and sliding up and down ! think the overall effect was well worth it though

   I like the interface for changing baubles and backgrounds - very slick!

   I'll be sure to follow-up with a review but agree with Codemattic that the interface is pretty kewl. Just found out that you can tangle the chain as well..nice.

   It is absolutely gorgeous. Bought it for the kids.

   Can you hint on how you did the rotating menus?

    thanks ... the top one is just a sprite - no physics, using trig to calculate the degree to rotate it on finger movement/tap.

    the lower one in chipmunk physics objects looks like a spider web ... then the baubles are actually just circle shapes that start off inside each web segment. because it's using physics the touch handling is a bit ... complex. If i just set the rotation based on finger position the wheel will rotate so fast the baubles will fly through the web walls because the position of the walls changes too fast for the bauble to have a chance to bounce off of them. So, to get around this i'm applying a huge torque to the wheel to move it in the direction of where it should be (current dragged to finger position, again using trig to work out radians to rotate) and then, as it get close to where it should be, throttling the velocity back. there's also a maximum possible velocity for the wheel. by doing this the wheel accelerates rapidly up to a max speed but doesn't fly past where it's meant to be. hope that's enough of a hint ;)

    Glad you enjoyed it! That's since managed to go global getting picked up by slashdot and gizmodo amongst others. Now if only the 100s of thousands of people who've seen it would buy the app!

    In the spirit of the season here are a few more codes (minor update just went though so have another batch to give out)

    Hi !

    Took the NJ97TNMTR934 and left à review.

    Cool app, I like how the menu is made.

    Two people working on it ? for how many time ?

    thanks for the review ... took us a week to write - me working 12hrs a day. A good chunk of that was getting to grips with chipmunk though!

    That CNET post has the best blog comment I've read in a long time: "I once removed my kidney and replaced it with a Fraggle by accident."

    The app looks very cool, and the quality of your promo video is fantastic. If you don't mind me asking, what kind of camera did you use?
