Blast from the past! A handful of sacred Power Macs in my elementary school computer lab had the shareware version of Glider installed ("Glider Trial", or "Trail" [sic] as my spelling-challenged classmates called it who were unfamiliar with trialware) and every one of us jockeyed for one of these machines as we filed into the room so that we could play it. Circa 1999 I somehow got my mom to ask a hapless Wal-Mart employee whether they made Glider from Casady and Greene written by John Calhoun for Windows. We got a weird look and a devastating "no". Sometime in the next year or two my best friend and I fixed up his Grandpa's old Mac Plus which happened to have an older full version of Glider on it which made me quite happy.
Hats off to you, Mr. Calhoun!
