At-least what scripting is concerned.
For now you can find the Collision Ghost Script in my main store and on MP. Demo located in my main store, entrance area (see picture above).
And at the Unik Event (from 7 to 28 October) you can find the Attach to Head Script. The demo is the pumpkin (click it). SURL: http://maps.secondlife.com/secondlife/UniK/32/224/1701
The Attach to Head Script requires the item to be copy and transfer. It however temporary attached the item to the avatar and does not give the item away (it doesn’t show up in the inventory).
For those who would like to get the same pumpkins here is where i got them: https://marketplace.secondlife.com/p/AB-Halloween-Pumpkins-FULL-PERM-1-LI-Strong-LODs/18162496
