[[File:9-bit, Single-Track Gray Code.gif|thumb|9-bit, single-track Gray code, displaying one degree angular resolution.]]
Since this 30 degree example was added, there has been a lot of interest in examples with higher angular resolution. In 2008, Gary Williams,<ref name="Experts_Exchange_Williams_2008">{{cite web |last1=Williams |first1=Gary |title='single track gray code' sought for encoding 360 degrees with 9 sensors |url=https://www.experts-exchange.com/questions/23594359/'single-track-gray-code'-sought-for-encoding-360-degrees-with-9-sensors.html#a22127642 |website=Experts Exchange|date=25 July 2008 }}</ref> based on previous work
<ref name="Etzion-Paterson_1996"></ref> discovered a 9-bit Single Track Gray Code that gives a 1 degree resolution. This gray code was used to design an actual device which was published on the site [[Thingiverse]]. This device<ref name="Thingiverse_9-Bit_Singletrack_Gray_Code_Rotorary_Encoder">{{cite web |last1=Bauer |first1=Florian |title=9-Bit Absolute Singletrack Gray Code Rotary Encoder |url=https://www.thingiverse.com/thing:4590077 |website=Thingiverse}}</ref> was designed by etzenseep (Florian Bauer) in September, 2022.
