Hi Byeong Sam, 1. a jpeg would be perfect for me to view this--but your file did not come through. pLease re-send from your own email address to me. thanks! 2. i wanted to ask you about speakers. the sound on my video piece is a really important part, very deep and ambient. i would like it to fill the hallway where the video is displayed. Scot (my boyfriend who works in sound) says i will probably need at least one power speaker. Will i need to reserve that from media center on my own? 3. Also about mounting the video projector. I don't know how to measure the distance i need the projector to be away from the wall. Can you help me with this? I know how large i want the image to be: about 2 feet by 2 feet on the white wall. I would love to do a ceiling mounted projector. Is that possible? Let me know! thanks thanks mariya
