Being still unsatisfied by aesthetics of the 2D codes, I created next code format with provisional name: Blotcode. You can use this link to generate random code: http://www.imatrix.lt/images/rolls.aspx Blotcode has error correction and can keep up to four byte long data string that is enough for majority of applications. I have implemented new way of bit presentation in that code: each bit can be visualized by at least two different shapes 
White element can be either white circle with black border or just nothing; black element can be either small or large black circle.
Great news is here – iMatrix is ported into SDK version beta 3!!! New iMatrix will be a little bit different from current toolchain based version because SDK has different set of frameworks and classes. Simulator based application cannot handle camera attached to my Mac Mini, but it does all the rest quite well and, that is very important, according to stricts rules Apple set.
Some time ago I have integrated ShotCode into iMatrix application. It is very nice fact! It proves flexibility of iMatrix design and wide possibilities on integration custom, proprietary, solutions widely available on a market. ShotCode is quite different from other 2D codes; it is circular
Personally, I am very proud of iMatrix success. It is very specific product with very narrow niche on a market but still has great feedback from useres worldwide! Today, I would like to give you some figures behind the project. As you could notice, I did not update application long time
