In Bloom Party 1993 was held in Kecskemät, Hungary for the PC and Amiga scenes and organized by Graffiti (C64), Twin Sectors Inc. (PC), 23 Celsius Crew (Amiga) and Guru BT. There is conflicting information for the date, as the invitation mentions 16-18 April 1993.
The attendance was around 500 people and there is mention of 120 releases (mostly graphics and music) at the party, the vast majority appearing to be lost, sadly.
The 23-25 April date, partial results and other details are from TSC/Phantom's report of the party in the diskmag Freestyle 7.
Other results based on results.txt from scene.org.
An Animation competition was held and had several entries in it, but all of them seem to be lost at the moment.
