APART from the hi-tech excitement of telescope models, ventilation systems and vehicle parts, the open day at the Lee Wai Lee Technical Institute was also filled with the laughter of children playing. Children from nursery schools were treated to special toys and games prepared by students in the Child Care programme. The ''Imaginative Corner'' was designed as an old Chinese village street where children entered a dream world and enjoyed a 15-minute ancient role-play. ''It took us a long time to prepare the setting,'' student Nillie Poon May-kee told Young Post . ''We needed a lot of ancient items and we wanted them to look real,'' Nillie said. The students put in a lot of time and effort to make the items themselves, including the food models, the equipment and other things on the set. They started working on the project after Christmas. ''The door was really difficult to build. We started at nine in the morning and didn't finish till 10 at night,'' said Yinny Wong Kwok-yin. Visitors were asked to write down their comments and suggestions on a booklet as they left the venue. ''We are happy to receive positive feedback from visitors. They said our corner looked real and the children really enjoyed it,'' Nillie said. Another point of attraction was the fish market where children played fishmongers and customers. The students provided aprons made from garbage bags, polystyrene ''ice'' and fish made from socks, gloves and bottles. On the other side of the institute, the work of Jewellery Design students, including sketches, renderings and final products, were on display. ''We were happy as visitors raised questions when they look at our work, which showed that they had a real interest in what we were doing,'' said Tang Yuk-yee, a student who was explaining the displays to visitors. ''I get disappointed if people just do a quick glance without showing any real interest,'' she said. The work of other design students, including print-making, photography, graphics and three-dimensional work, were also exhibited in the school hall. First-year students in Visual Communication set up their display corner as a street scene where a paperboy was climbing up the partition, trying to have a peep at the students' work of modern art. ''It took us a whole day to decorate our stall with recycled materials,'' said Barry Tang Wing-kai.
