I put some Mosaic derivations to my github[1][2][3]

[1] multicast mosaic ("mMosaic") https://github.com/roytam1/multicast-mosaic

[2] VMS Mosaic https://github.com/roytam1/vms-mosaic

[3] mosaic-CK https://github.com/roytam1/mosaic-ck

Just for the record, the remark in the webpage linked from that github saying that in 1996 "gopher was in its heyday" doesn't seem right to my memory. Gopher heyday in 1992-93? Sure! But gopher faded with the rise of Mosaic throughout 1994 iirc...
