His name is Hal Lasko, his nickname Grandpa. What he did for living is something we will probably never see again – he was a graphic artist back when everything was done by hand. He then had to retired and his caring family had the genius idea to introduce him to the computer and especially to Microsoft Paint.
Since then Grandpa spends ten hours a day moving pixels around his computer paintings. Some would call his work pointillism, others 8-Bit art but it might be a bit of both.
Anyway, another inspiration that is Hal Lasko, The Pixel Painter. We have included below a video interview of the artist plus a few examples of his works.
