瓶をなぞって色砂を注ぎ、層を重ねて模様をつくるアプリです。 観光地の土産物にある「砂絵ボトル」を、指先で作れます。 ■ 実在する砂の色で作れる 色を「きれいな色」として並べるのではなく、実際にその色をした砂浜・砂丘の砂を収録しました。選ぶと、どこの砂で、なぜその色なのかが表示されます。 ・日本の砂 — 鳥取砂丘、琴引浜の鳴き砂、竹富島の星の砂、屋久島いなか浜、九十九里浜、田子の浦 ・世界の砂 — ホワイトヘブン(オーストラリア)、シェルビーチ、ボラカイ、レイニスフィヤラ(アイスランド)、プナルウ(ハワイ)、カイハルル ・めずらしい砂 — かんらん石の緑(ハワイ/ガラパゴス)、有孔虫のピンク(バハマ/バミューダ)、ガーネットの紫、佐渡の砂金 星の砂が有孔虫の殻そのものであることや、ピンクの砂浜の色が赤い有孔虫によることなど、一行の解説を添えています。 ■ 砂は一粒ずつ落ちて積もる 画像を貼り付けるのではなく、粒をひとつずつ計算しています。注いだ砂は山になり、崩れ、先に入れた色の上に重なります。端末を傾けると、積もった層が流れて模様が変わります。 ■ 作れるもの ・器は12種類(とっくり、フラスコ、たまご、砂時計、ハート、ねこ など) ・砂の色は54色。既存の色の組と、実在の砂の組から選べます ・砂の量は3段階。細く重ねる層と、一気に埋める層を使い分けられます ・注いでいる間は砂の音が鳴ります(音は切り替えられます) ■ 作った瓶は棚に並ぶ 保存した瓶は棚に立てて並びます。あとから開いて続きを注ぐこともできます。画像として書き出して残せます。 ■ そのほか ・インターネット接続は不要です。すべて端末の中で動きます ・アカウント登録やログインはありません ・個人情報を収集しません
