It's possible to install GNU/Linux on Explorer units thanks to Google following the GPL and releasing kernel sources[0]. It's also possible to get AOSP running on an Explorer unit, and it works well enough on Android Lollipop at least[1]. Some people at PostMarketOS have even gotten recent Linux kernels to work on Glass[2], although the last time I tried (last year), I wasn't able to get anything to draw to the framebuffer after about 6 hours of effort. Finally, the original GlassOS was Android based. The stock kernel and applications have been extracted and are floating around[3].
