@nihilazo Awesome, I was thinking of doing the same to my Tolino reader. But I haven't even figured out how to flash or add software to it. Have you got any code to go with that screenshot?
@stapper I'm not sure about the tolino, you'd have to look specifically for that device. On the kobo, you can install nickelmenu and then the gemini client is just a go program launched from that, that uses the fbink library to access the kobo's framebuffer. Some quick searching makes the tolino appear to be running android, it's worth looking on mobileread: https://www.mobileread.com/forums/forumdisplay.php?f=279
