On Saturday we were invited to draw at the launch party of this new Prague-based audio visual collective.In the afternoon at VILA Štvanice (above) there was a picnic with music outside the theatre, continuing until late in the night with more live music, DJs and installations both inside the theatre and outside on the grass and among the trees. We set up the Tagtool to cover the whole of the building with the entrance to the bar in the centre and once it got really dark I began to draw.As there was virtually no ambient lighting affecting this side of the building and the only illumination for people sitting outside was coming from the laser and led light installations on the grass and among the trees in the park, it was not difficult to produce dramatic effects with the Tagtool. But as well as drawing in full colour I also worked in black and white, making the building almost disappear in the darkness.At the start of the evening the live music was outside but later the action moved inside the theatre, although many people remained drinking at the tables outside the bar and sitting on the grass among the led lights and laser installations.Both the weather and the location were ideal for drawing and the relaxed party atmosphere meant that I could draw at my own pace and also stop from time to time and join the party. Some people who hadn’t seen the Tagtool before came and wanted to know about it. Because they were interested in having a demonstration, instead of packing up and going home, we had a late night impromptu ‘have a go’ session! I was sorry that we didn’t have our Tagtool mini with us as most people were right-handed and it’s not easy to draw ‘cross handed’. Unfortunately I don’t have any photos from this fun session but at the very end of the night I took the two photos below….One of the party-goers had drawn a kaleidoscope of colours over the whole building. Then I drew this black silhouette on top of his drawing and he posed with his arms in the air while his friends took photos for him – great fun and a very nice ending to a great evening!
