something so exciting that I could not keep it to myself

ok...... so I just read in Vogue Knitting that a product design student has invented knitting needles that not only keep track of how many rows have been knit, but also how many stitches have been knit. THAT'S F#&%ING AMAZING! think about it...... I could knit without having to stop after each row to click my counter...... why has this not been invented before... this is exciting and i know it's nerdy of me to think so
