After a three year absence, Panic is returning to Macworld Expo next week. The company will have a limited supply of free “Panicdisc” CD-ROM’s to hand out, which will contain all of their software demos, along with tons of extra CandyBar icons and Audion faces. The CD-ROM is also the only way to obtain a copy of B360, the company’s never-released 1982 arcade game, which is now ported to Mac OS X. Also, anyone who purchases or registers any of Panic’s software (Transmit, CandyBar, Desktastic or Audion) at their Macworld Expo booth (#1748) will receive a free Panic Shirt — one of four new styles for each day of the show. If you have already bought a Panic product, and can be one of the first 15 people to visit Panic’s booth each morning, you too can score a free t-shirt by providing a serial number.
