That was great. 1995 era effects (vectorbobs, plasmas, Gouraud shading etc), but still neat to think of it running in the Java VM on whatever CPU a Blu-ray player houses. Also the author says you can use your remote to control some of the effects.
Oh yeah, it’s definitely going for oldschool appeal. There’s something oddly compelling about running demos in weird and ill-fitting places. Mac Classic[1], mIRC script[2], TI-83 graphing calculators[3]… it’s got to be a similar appeal to porting DOOM to MP3 players, or Bad Apple!! to Atari Lynx.
