I once had a fiddle with Bryce 3D & Simply 3D software packages a long time ago (they were full version freebies on some magazine coverdiscs).
This was one of the results – which I later used as my Windows 95/98 Startup screen (with a little bit of conversion)
Want it for your own Windows 95/98 system? Download it here!
Note: The ZIP file includes the original pic and your own copy of the startup logo system file (with loading bar animation along the bottom of the screen) for those of you who may still be using those versions of Windows out there… *shudders*…
