Minecraft creator Marcus 'Notch' Persson has Tweeted work-in-progress screenshots of dragons flying around in his hugely successful world-building indie game.
Is it a taster of an upcoming content addition for the title? Or a cheeky poke-in-the-eye directed at Skyrim publisher Bethesda with whom he's embroiled in a well-documented legal tussle?
Notch wasn't giving much away elsewhere on his Twitter feed, merely stating he was "developing epicness for minecraft!"
"And texturing this dragon is going to be.. interesting," read a later Tweet. "I'll keep working on this way into this weekend, probably. :-D"
